Product details

It is designed specifically for motor protection — the MA trip provides short-circuit protection (magnetic) only, with no thermal overload element, so it coordinates with an external motor starter or overload relay.

The MA trip unit is magnetic-only, so it responds to short-circuit currents but does not provide thermal overload protection; that is left to the motor starter or soft starter downstream. At 480 V AC the Icu is 35 kA (UL 60947-4-1), and at 600 V AC it drops to 10 kA — still sufficient for many 480 V motor loads. The 3-pole, 3D protected poles configuration means all three poles are protected against short circuits.

The toggle control gives clear visual indication of ON/OFF/TRIPPED status. IP40 front face and IK07 impact resistance handle typical panel conditions.

Frequently asked questions

What is C16F3MA100 used for?

It is a motor protection circuit breaker with a magnetic-only trip unit, used to provide short-circuit protection for motor branch circuits in industrial panels. It coordinates with an external overload relay or motor starter.

What breaking capacity does C16F3MA100 have at 415 V AC?

36 kA Icu at 380/415 V AC per IEC 60947-2, which is the 'F' breaking capacity code.
