WARNING: This product can expose you to chemicals including DINP, which is known to the State of California to cause cancer, and DIDP which is known to the State of California to cause birth defects or other reproductive harm. For more information go to:

• www.P65Warnings.ca.gov.

The product has been designed for environment A (Class A, IEC 60947-1). Use of this product in environment B (Class B, IEC 60947-1) may cause unwanted electromagnetic disturbances in which case the user may be required to take adequate mitigation measures.

Installation

1. Turn off all power supplying this equipment before working on or inside equipment.
2. Trip the circuit breaker (Figure 1, a–c).
3. Use a properly rated voltage sensing device to confirm power is off.
4. Remove the handle extension (d).

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

Breaker Installation

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.

1. Check the electrical clearances (Figure 2, a). Insulate the circuit breaker if necessary (b–c).
2. If dimension “A” is less than 0.56 in. (14.2 mm), attach fiber insulating plate (not provided) to the enclosure cover.
3. Insulation is required if circuit breaker side is < 4.13 in. (105 mm) from metal.
4. Install the circuit breaker (Figure 3, a–b).

I-Line™ Circuit Breaker Installation

HAZARD OF EQUIPMENT DAMAGE

• Do not adjust jaws.
• Do not remove joint compound.
• If necessary, use Square D joint compound PJC7201.

Failure to follow these instructions can result in equipment damage.

1. Rack the circuit breaker onto the bus (Figure 4 (a–c).
2. Tighten the mounting bracket screw (d–e).

Cable Installation

NOTE: If the circuit breaker has terminal nuts installed, remove terminal nuts and install lugs as directed in the instructions shipped with the lug kit.

NOTICE

HAZARD OF FALSE TORQUE INDICATION Do not allow conductor strands to interfere with threads of wire binding screw. Failure to follow these instructions can result in equipment damage.

TABL. 2 : Lug Information

1. Conductors must be cut square for secure termination

NOTE: See Table 2 for strip lengths and torques.

1. Perform the conductors to their final configuration. Strip the conductor ends (Figure 5, a). Do not nick strands.
2. Install the cables in the lugs and torque the wire binding screws (b–c).
   • Install wire larger than 12 AWG in the centre of the channel (d).
   • Install 14–12 AWG wire on the side of the channel (e) on all lugs to avoid damage to the wire.

Bus Installation

NOTE : If terminal nut inserts are not installed, install the terminal nut inserts as directed in the instructions shipped with the terminal nut kit.

1. Install the bus using the supplied hardware (Figure 6, a–c).

Accessory and Control Wiring Installation

1. Remove accessory cover (a).

2. Remove the accessory devices from the corresponding accessory compartments (b).
   NOTE: Installation of overcurrent trip switch (SDE) requires installation of the SDE actuator, not provided.

3. Install control wiring (c) to the accessories.
   NOTE: All diagrams show the circuit breaker in tripped position.

NOTICE

HAZARD OF EQUIPMENT DAMAGE

• Tighten all accessory cover screws to the stated torque.
• Do not over-torque screws.
• Do not use power equipment to torque screws.

Failure to follow these instructions can result in equipment damage.

• Route the wiring (Figure 8, a).
• Replace the accessory cover, being careful not to pinch the wires when installing the cover.
• Replace Visi-Trip handle on the proper orientation, or handle extension (d).

Plug-On and Drawout Circuit Breakers

See wiring information provided with plug-in base. If accessories are field installed, follow the instructions provided with a 9-wire connector.

NOTE : Confirm that the catalog number printed on the side of the accessory label (Figure 9, a) matches catalog number printed on the accessory cover (b).

Mark on the side accessory label (a) which device was installed.

Circuit Breaker Removal

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

Operation

• Press push-to-trip button (Figure 10, a) at installation to check operation.
• Repeat once a year to exercise circuit breaker.
