{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"3VA1132-5EF32-0HA0","brand":"Siemens","brandSlug":"siemens","productSlug":"3VA1132-5EF32-0HA0","canonicalUrl":"https://aoctrl.com/siemens/3VA1132-5EF32-0HA0","factsUrl":"https://aoctrl.com/api/mcp/products/3VA1132-5EF32-0HA0","rawCanonicalId":null},"summary":{"shortDescription":"Siemens SENTRON 3VA1 series, 3VA1132-5EF32-0HA0, molded case circuit breaker (MCCB), 3-pole, 32 A, TM240 thermal-magnetic overcurrent release, shunt trip (STL), line protection design, breaking capacity 187 kA at 240 V AC.","salesMarkdown":"## SENTRON 3VA1 MCCB — 32 A, 3-pole, TM240, Shunt Trip The Siemens 3VA1132-5EF32-0HA0 is a SENTRON 3VA1 series molded case circuit breaker (MCCB) rated for 32 A continuous at 40 °C, with a 3-pole configuration and a TM240 thermal-magnetic overcurrent release. The integrated shunt trip (STL) allows remote tripping via a control voltage, enabling emergency-off or interlock functions without an external undervoltage release. ## Breaking Capacity — Rated for High-Fault Distribution This MCCB delivers 187 kA interrupting capacity at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The 187 kA rating at 240 V makes it suitable for high-fault-capacity main breakers in industrial panelboards or as a feeder breaker downstream of large transformers — it clears a bolted fault without cascading upstream. ## Thermal Derating — 32 A Continuous, Stable to 70 °C Rated 32 A from 40 °C through 50 °C ambient, the 3VA1132-5EF32-0HA0 derates to 31 A at 55–60 °C and 30 A at 65–70 °C. The flat 32 A band up to 50 °C gives headroom in a typical 40 °C panel environment — no need to upsize the frame for a 32 A load unless ambient exceeds 50 °C. The -25 °C lower limit suits unheated electrical rooms in temperate climates; for cold storage or outdoor enclosures below -25 °C, verify the ambient at the breaker location. ## Panel Fit — 3-Pole, 76.2 mm Wide, Shunt Trip The 3VA1 frame measures 76.2 mm wide (3 inches), 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that mounts on a DIN rail or bolts directly to a panel backplate. The shunt trip (STL) release occupies the auxiliary slot on the right side of the breaker. It requires a separate control voltage (typically 110–240 V AC/DC, verify from the shunt trip coil rating) and a maintained signal to hold the breaker closed — loss of control voltage trips the breaker. No undervoltage release is fitted, so the breaker latches mechanically without control power. ## Lifecycle & Sourcing — Active Production, Quoted to Order For BOM freeze or multi-year spares planning, this part is a standard catalog item with no imminent phase-out signal. If a second-source or alternate form-fit-function replacement is needed, the closest peer in the same 3VA1 family is the 3VA1110-5ED32-0AA0 (lower frame rating, different release) — but the 3VA1132-5EF32-0HA0 is the primary target for this order code.","metaTitle":"Siemens 3VA1132-5EF32-0HA0 SENTRON MCCB, 32A, 3-Pole, 187kA","metaDescription":"Siemens 3VA1132-5EF32-0HA0 SENTRON molded case circuit breaker, 32A, 3-pole, TM240 release, shunt trip.
