NEW ARRIVAL: Siemens SENTRON 3VA9988-0AB12 Tripped Signaling Switch Now Available
Model Description
We are pleased to announce the immediate availability of the Siemens SENTRON 3VA9988-0AB12 tripped signaling switch, a compact 7mm-wide auxiliary accessory engineered for 3VA1 and 3VA20-26 molded case circuit breakers. This HQ-type changeover contact device (1NO+1NC) mounts directly on the breaker’s accessory slot and provides reliable status indication when the main contacts trip due to overload, short-circuit or manual operation. Rated for thermal current of 6A with full AC-12 (6A @ 240V AC) and DC-12 (6A @ 24V DC) capability, the switch delivers robust signaling for PLC inputs, alarm circuits and remote monitoring systems. Its slimline dimensions (56×7×30mm) and lightweight 27.5g construction integrate seamlessly into control panels without increasing depth or requiring additional brackets .

Key Features
The 3VA9988-0AB12 delivers exceptional electrical performance with 4kV surge voltage resistance and 690V rated insulation voltage, meeting IEC 60947-5-1 standards for auxiliary contacts. Pollution Degree 3 and Overvoltage Category III certification ensure reliable operation in dusty, humid or harsh industrial environments. Mechanical life exceeds 10,000 operations, while the non-repairable design guarantees maintenance-free service exceeding 20 years. The unit features screw-type terminals accepting 0.5–1.5mm² (AWG 20–16) conductors with 0.4–0.5Nm tightening torque, and front-mounted test button allows functional verification without breaker disassembly. CE, cULus, CCC, EAC and RoHS approvals (valid since June 2012) validate global deployment, while IP20 finger-safe construction enhances installer safety .

The SENTRON 3VA9 portfolio offers comprehensive breaker protection functions in identical 7mm footprints. 3VA9907-0BB25 provides standard auxiliary contacts for basic status signalling, while 3VA9910-0BB25 adds an alarm contact that latches on fault conditions. For remote tripping applications, 3VA9912-0BB25 delivers shunt-trip capability, and 3VA9908-0BB25 (AC) or 3VA9908-0BB24 (DC) provide undervoltage release functions for generator backup systems. 3VA9916-0BB25 enables mechanical interlocking between two breakers. All variants share common mounting geometry, terminal layouts and certifications, enabling panel builders to standardise cut-outs and select functions without mechanical redesign across 3VA1 (100–160A) and 3VA2 (100–630A) breaker families .
