PowerPacT H and J Frame Electronic Trip Circuit Breaker

Product Information

This product is the PowerPacTTM H- and J-Frame Electronic TripCircuit Breaker. It is a device that automatically interrupts an electrical circuit during an overload or short circuit. This circuit breaker is equipped with a Visi-TripTM LED handle that helps in quickly locating a circuit breaker that requires attention. The product comes with internal accessories that need to be installed prior to installing the circuit breaker. It is important to note that failure to follow the instructions may result in death or serious injury.

The required specifications for installation include screws, extension blanks, lugs, and cords. The product has different Ir (x Io) and Io (A) values that depend on the type of cord used. The product also has a DINP chemical that is known to cause cancer and DIDP chemical that is known to cause birth defects or other reproductive harm.

Product Usage Instructions

Before starting the installation, read and understand all instructions provided in the Instruction Bulletin. Turn off all power supplying this equipment before working on or inside equipment. Install the internal accessories as instructed in the bulletins shipped with each accessory. Remove any installed handle extension if it will interfere with the enclosure door closing.

When performing annual maintenance, operate the push to trip button (if equipped) to verify the Visi-Trip functionality. Cycle the circuit breaker from tripped to OFF, and then from OFF to ON and take note of the battery health.

It is important to follow the precautions provided in the Instruction Bulletin to avoid death or serious injury. For more information about the chemicals used in this product, visit: www.P65Warnings.ca.gov.

Installation

Turn off all power supplying this equipment before working on or inside equipment.
Trip the circuit breaker (Figure 1, a–c).
Note: All internal accessories must be installed prior to installing the circuit breaker.
Install the internal accessories (d) as instructed in the bulletins shipped with each accessory.
Remove any installed handle extension (e) if it will interfere with the enclosure door closing.

Visi-Trip™
The Visi-Trip LED handle aids in quickly locating a circuit breaker that requires attention. Inspect the handle position for circuit breaker trip indication. The Visi-Trip handle will flash an LED light as described in Table

Note: When performing annual maintenance in accordance with MCCB Field Testing and Maintenance Guide
(0600IB1201), operate the push to trip button (if equipped) to verify the Visi-Trip functionality. Cycle the circuit breaker from tripped to OFF, and then from OFF to ON and take note of the battery health. See Table 2.
Wait five seconds between handle operation and push-to-trip button operation to ensure that the Visi-Trip handle is on standby mode. Tripping the circuit breaker too soon after toggling may result in the Visi-Trip handle not operating as intended.1

TABL. 1 :

Light Pattern	Indicator /
Fast flash for two seconds.	Battery low (20% remaining).
Long duration slow flash (continuous flash up to for six hours).	Inspect the

handle position for circuit breaker trip indication. 1

Refer to the Schneider Electric Frequently Asked Questions page. https://www.se.com/us/en/faqs/home/ for more information.
If a nuisance LED flashing occurs on ON or OFF position, it can be reset by toggling the circuit breaker. If toggling the circuit breaker is not desired, LED flashing will reset after six ours.

Individually-Mounted Circuit Breaker Installation
DANGER: HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Install circuit breaker so minimum clearance distance to grounded metal is maintained.
Failure to follow these instructions will result in death or serious injury.

Check electrical clearances (Figure 2, a–c).

Circuit Breaker Removal

Turn off all power supplying this equipment before working on or inside equipment.
Remove circuit breaker in reverse order of installation.

Troubleshooting

If problems occur during installation, refer to the following guide. If trouble persists, contact the local field office.

DANGER: HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

This equipment must be installed and serviced only by qualified electrical personnel.
Troubleshooting may require energizing auxiliary devises with a test power supply. Make sure that the power supply is Off (O) before connecting or disconnecting it to the auxiliary device.
Qualified persons performing diagnostics or troubleshooting that require electrical conductors to be energized must comply with NFPA 70 E – Standard for Electrical Safety Requirements for Employee Workplaces and OSHA Standards -29 CFR Part 1910 Subpart S -Electrical.

Failure to follow these instructions will result in death or serious injury.

Condition	Possible Causes	Solution
Circuit breaker fails to stay closed.	Short circuit or overload on system.

Check system for short circuit or overload.
Circuit beaker trips, but no short circuit or overload is evident.| Voltage is below undervoltage trip setting.| Check system for low voltage.
Push-to-trip button does not trip circuit breaker.| Circuit breaker already tripped.| Move circuit breaker handle to reset then to on (I).
Circuit breaker cannot be opened manually.| Damage to current path.| Contact local field office.

Electrical equipment must be installed, operated, serviced, and maintained only by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this material.
