The Siemens SENTRON 3VA2110-5JP32-0CL0 is a 3-pole molded case circuit breaker rated 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, then drops to 75.6 kA at 500 V and 3.7 kA at 690 V. That 187 kA figure at 240 V means it can safely interrupt a fault current up to that level without cascading to upstream gear — critical for high-fault panels near large transformers or utility feeds.
Panel fit and integration
Mounts on a DIN rail or panel base. Dimensions: 105 mm wide, 181 mm high, 86 mm deep. That 86 mm depth is the dimension to check against gland-plate clearance or shallow enclosures — the breaker body projects that far from the mounting surface. Accepts 0.2–2.5 mm² conductors on the spring-cage terminals. Includes an undervoltage release (UVR) and a configurable auxiliary switch block: 2 auxiliary switches + 1 trip alarm switch + 1 electrical alarm switch. The basic switch assembly carries order code 3VA21105JP320AA0. Communication function is built in — no separate comm module required for basic status reporting.
Lifecycle and sourcing posture
Current-production lifecycle stage — no phase-out notice on record. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time. For a BOM-freeze or line-down spare, this is a straight-in replacement for the same order code.
