Product details

Current rating holds at 20 A from 40 °C through 55 °C ambient, then derates to 19 A at 60–70 °C. Power loss is 12 W maximum — relevant for thermal budget in a sealed enclosure.

Deployment context

The 4-pole configuration suits three-phase systems with a switched neutral. Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — the width of a standard 4-pole MCCB footprint. Verify busbar and mounting hole pattern against the existing panel layout; the depth leaves clearance for rear-connected cables.

Frequently asked questions

What does the TM220 release designation mean?

TM220 indicates a thermal-magnetic overcurrent release — thermal element for overload protection, magnetic element for short-circuit protection. The '220' is a Siemens release code for a specific trip curve and rating.
