MT3700T - 700 Amp Trip Unit Description
MT3700T - 700 Amp Trip Unit
When your circuit breaker needs attention, replacing the right component can make all the difference. For maintenance teams working with established electrical equipment, the challenge is often finding a trip unit that matches the existing breaker frame, electrical ratings, and protection requirements without changing the original system configuration.
The MT3700T 700 Amp 3-Pole Thermal Magnetic Trip Unit is designed for use with MDL and HMDL circuit breaker frames. Rated at 700 amps and 600VAC, this Type MT trip unit provides thermal-magnetic protection for compatible three-pole circuit breakers. It's a practical component to evaluate when servicing existing electrical distribution equipment that requires this specific trip unit arrangement.

Material Compliance and Certifications
Electrical protection components need to match the equipment they're installed in. With the MT3700T thermal magnetic trip unit, the first compatibility check is the circuit breaker frame.
The supplied product information identifies the MT3700T for MDL and HMDL frames only. Compare its 700-amp rating, three-pole configuration, and adjustable magnetic trip characteristics with the existing breaker assembly and the manufacturer's approved trip unit combinations.
All installation, adjustment, inspection, and maintenance work should follow applicable National Electrical Code (NEC) requirements, local electrical regulations, and the manufacturer's instructions.
