It occupies 7 mm of DIN-rail width and carries a thermal current rating of 0.3 A. This is a signaling accessory, not a main power path component — it reports the breaker's tripped state via a changeover contact set. The 0.3 A rating covers the signal load, not a motor or heater circuit. ## Switching capacity and contact ratings The changeover contacts are rated 0.3 A at 12 V and 24 V under AC-12 and AC-15 duty classes — the same 0.3 A holds across both resistive and light inductive AC loads at those voltages. For DC switching, the ratings drop: 0.1 A at 12 V and 24 V under DC-12 (resistive), and 0.07 A at the same voltages under DC-13 (solenoid/contactors). The minimum operating voltage is 24 V DC. The 0.07 A DC-13 rating is the limiting case — if the switch signals a DC contactor or solenoid, stay under 70 mA at 24 V. The AC-15 rating at 0.3 A covers most PLC digital input and indicator lamp loads. ## Isolation and environmental specs Dimensions: 7 mm wide, 30 mm deep, 56 mm high. The 7 mm width is a single modular DIN-rail unit — it snaps into the same rail as the 3VM breaker it signals. Stripped length is 15 mm (0.6 in) for the connection wires.","metaTitle":"Siemens 3VM9988-0AB13 SENTRON Tripped Signaling Switch, 0.3","metaDescription":"Siemens SENTRON 3VM9988-0AB13 tripped signaling switch for 3VM breakers. 7 mm wide, 0.3 A thermal current, changeover contacts.
