Breaking capacity is the headline figure here: 121 kA at 240 V AC, tapering to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The TM220 trip unit means thermal-magnetic, fixed-trip, no electronic adjustment. The '220' designates the frame size and trip curve family. No undervoltage release, no shunt trip, no communication module — this is a straight-ahead thermal-magnetic breaker for basic overcurrent and short-circuit protection.
Thermal performance and panel fit
At 60 °C and 65 °C it derates to 15 A; at 70 °C it stays at 15 A. No ground-fault monitoring, no communication function — this is the base-line-protection variant.
