That's your remote or automated trip signal: from a safety relay, a PLC output, an emergency-stop circuit, or a supervisory system that needs to kill power without a human pulling the handle. The coil draws 40 VA on AC and 40 W on DC at maximum, so the control transformer or DC supply feeding it needs to cover that inrush. Physical envelope: 65.1 mm tall, 25.7 mm wide, 31.2 mm deep. That's the left-side accessory slot depth on the 3VA frame — it doesn't add width to the breaker itself. Stripped length for the screw terminals is 10 mm (0.4 in). Three connection slots on the release. No DIN-rail space consumed beyond what the host breaker already occupies. Product status is Active. This is a current-production Siemens catalog item, not a phase-out or NRND line. It's the standard shunt trip for the 3VA1 and 3VA20-3VA25 breaker family — no substitution needed, no last-time-buy window to watch.","metaTitle":"Siemens 3VA9988-0BL32 Shunt Trip, 110-127 V AC/DC, 40 VA","metaDescription":"Siemens SENTRON 3VA9988-0BL32 shunt trip for 3VA1/3VA20-3VA25 breakers. 110-127 V AC/DC, 40 VA/40 W, 4 kV surge.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm quote with lead time."},{"question":"What is the closest functional second-source to 3VA9988-0BL32?","answer":"The 5SY4140-7 is a SENTRON miniature circuit breaker, not a shunt trip — it's a different product class entirely. There is no direct second-source for the 3VA9988-0BL32 outside Siemens' own 3VA accessory line. The shunt trip is specific to the 3VA1 and 3VA20-3VA25 breaker frame and has no functional equivalent from other brands."},{"question":"Will 3VA9988-0BL32 drop into a panel specified around 5SY4140-7?","answer":"No. The 5SY4140-7 is a 1-pole miniature circuit breaker (18 mm wide, DIN-rail mount). The 3VA9988-0BL32 is a shunt trip accessory that mounts inside a 3VA molded case circuit breaker frame. They serve completely different functions and mounting locations — no direct interchange."},{"question":"What compliance documentation does Siemens provide for 3VA9988-0BL32?","answer":"As a current SENTRON accessory, the 3VA9988-0BL32 carries the standard Siemens compliance documentation package including CE marking for the European market. Specific certifications (UL, CSA, CCC, EAC) depend on the host breaker assembly and regional configuration. Request the manufacturer's declaration or datasheet with your RFQ for jurisdiction-specific documentation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA9988-0BL32","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA9988-0BL32 when reusing this data.
