The thermal-magnetic curve stays flat across the 40 °C to 50 °C band — still rated 20 A — then derates gradually to 18 A at 70 °C. The 3VA1020-2ED36-0JH0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into a SENTRON panelboard or a separate DIN-rail adapter. That gives you two independent signal paths for status feedback (open/closed) and a dedicated alarm contact that changes state only on a trip event — useful for remote annunciation without tying up a PLC input on the breaker's main position. ## Auxiliary release and accessories The integrated auxiliary trip accessory is order code 3VA9688-0BL32 — that's the part number to add if you need a separate undervoltage release or additional shunt trip capability.","metaTitle":"Siemens 3VA1020-2ED36-0JH0 SENTRON MCCB, 20 A, 52.5 kA","metaDescription":"Siemens SENTRON 3VA1020-2ED36-0JH0 molded case circuit breaker, 20 A rated, 52.5 kA at 240 V. 3-pole line protection with TM210 release.
