- The device is to be installed only on the load side of branch circuit protection.
- Set the current adjustment not more than the rated input current of the control transformer.
- Use only in the specific supply voltage system as marked on the device.
Motor Protection/Circuit Breaker
This device meets the requirements of IEC 60947-2 as a circuit breaker. It is
cULus listed (UL and CSA approved) as:
- A Manual Motor Controller with optional approvals for Group Motor, Motor Disconnect and Tap Conductor Protection.
- A Manual, Self-Protected Combination Motor Controller (Construction Typ. E).
All installations, commissioning and maintenance must be carried out by qualified personnel, taking local regulations into account.
140MT-D9V-…
VFD output frequency < 400Hz, PVM frequency fc < 4kHz VFD output frequency <
400Hz, PVM frequency fc < 4kHz Current setting: VFD in = max. input current,
VFD out = rated motor current.
For more details see the technical specifications.
Not applicable for 140MT-D9V
140MT-D9N do not provide thermal protection for themselves nor for downstream
components. A separate protective device against thermal overload must be
installed, e.g. an O/L relay as part of a starter combination. Refer to the
derating specification for heavy-duty starting.

Ex relevant information
Explosion Application Cat. No. Type Range: Bul. 140MT-C3E-…, 140MT-D9E-…,

The Ex protection function of the 140MT-C / D devices (Circuit breaker with
contactors as starters outside the Ex zone with connection to the Ex zone) is
a thermally delayed release device with phase failure protection so that the
motor starter acts as a safety device (protective device for indirect
temperature monitoring) to protect motors to avoid impermissible temperatures
can be used.
Possible Type of Ignition in according to the Zone:
- For Mining: DB, web, and pxb
- For Gas: db, eb and pxb
- For Dust: tb and pxb
I (M2) [Ex eb Mb]
II (2) GD [Ex eb Gb]
Multiple of current setting limits for ambient air temperature compensate time-delay overload relays:
Ex Ambient Specifications:
- Operation at Ta = -25 °C up to +60 °C
- Storage at T= -40 °C up to +80 °C
- SIL 1 necessary requirements for the environment e.g. overvoltage category
Ex Installation and Maintenance:
- Use 60079-14 (for dust additional 61241-14) for Project engineering, selection, and installation
- Use 60079-17 for Inspection and maintenance
- No repairing of the 140MT-C/D devices allowed (Because the Ex protection function is no longer guaranteed!)
- Where automatic restarting after a failure is not permitted, the user must take suitable measures to prevent restarting.
- With the aid of the device’s test function, the tripping mechanism can be tested in the de-energized state.
- The cable type and the conductor cross-section of the current leads must be selected so that the thermal limiting temperature for the connecting cables is not exceeded.
- It could be proved in all cases that the motors are safely switched off.
European Hazardous Location Approval. The following applies to products marked
II (2) GD and I (M2): Are Equipment Group I and II, Equipment Category 1G, 2G,
1D, 2D, and M2 and comply with the Essential Health and Safety. Requirements
relating to the design and construction of such equipment are given in Annex
II to EU Directive 2014/34/EU. See the EU declarations of conformity, safety
instructions, and certificates on the links below.
Safety devices intended for use outside potentially explosive atmospheres
caused by gases, vapors, mist, (coal) dust, and methane are likely to occur in
normal operation, but are required for, or contributing, the safe functioning
(also during expected malfunctions) to equipment and protective systems with
respect to the risk of explosion. Such locations correspond to Zone 1, Zone
21, and Mining classification according to ATEX directive 2014/34/EU.

Warnings
WARNING: The opening of the branch-circuit protective device may be an
indication that a fault current has been interrupted. To reduce the risk of
fire or electric shock, current-carrying parts and other components of the
controller shall be examined and replaced if damaged.
