Product details

The TM-D trip combines a thermal element for overload protection and a magnetic element for short-circuit response — no electronic adjustments, just fixed-curve reliability.

Category A utilisation means it's not intended for cascading (no intentional short-time delay), so selectivity with downstream devices relies on the thermal-magnetic curve gap. Pollution degree 3 (IEC 60664-1) suits it for industrial panels where conductive dust or condensation is expected. IP40 front face keeps tools and fingers out; the backplate mount and front connection terminals suit panel layouts where side access is tight.

Integration notes

Mounts on a backplate in horizontal or vertical orientation. 12-module 9 mm pitch width (108 mm) fits standard DIN-rail-mount enclosures with adapters. Connection terminals accept compression lugs or busbars; neutral position is left. The toggle control and flag indicator for auxiliary contact presence give clear local status without opening the panel door.

Frequently asked questions

Where can I buy C12F4TM160B and how is it quoted?

The C12F4TM160B is sourced and quoted to order through independent distribution. Availability and current pricing are confirmed at quote time against an RFQ.

What standards does C12F4TM160B comply with?

The C12F4TM160B complies with EN/IEC 60947-2 for low-voltage switchgear and controlgear, with suitability for isolation per that standard. Pollution degree 3 per IEC 60664-1 and IK07 impact resistance per IEC 62262.

What is the breaking capacity of C12F4TM160B?

The C12F4TM160B is rated 36 kA at 415 V AC (performance level F). That's the maximum fault current it can safely interrupt at that voltage.

What trip unit does C12F4TM160B use?

It uses a TM-D thermal-magnetic trip unit rated 160 A at 40 °C. No electronic adjustments — fixed overload and short-circuit curves.
