The TM220 overcurrent release combines a thermal element for overload protection and a magnetic element for short-circuit response; it's a fixed-trip design, so the 200 A rating is the breaker's identity, not an adjustable range. Breaking capacity is where this breaker earns its panel space: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. Temperature derating is built into the spec: the breaker holds 200 A from 40 °C through 50 °C, then drops to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C.
The 3VA1220-5GE42-0AA0 measures 70 mm deep, 140 mm wide, and 158 mm high — a compact footprint for a 200 A 4-pole MCCB. It's designed for DIN-rail mounting or direct screw-fixing to a backplate.
