A3B

Thermal Cutout/ Regulator/Limiter FEATURES – Precision switching – High sensitivity – Broad application – Wide range of housings, connections and fixings – Designed for dirty situations A3 A3A A3K A3K2 A3K3 DESCRIPTION Types A3, A3D, A3L, A3DL, A3DS, A3A, A3DA, A3SD, A3AS, A3K, and A3K1 are designed for operations as thermal cutouts, temperature regulators or overheat protection. Type A3K2 is a double pole thermal cutout or over-temperature protector. Type A3K3 is a thermal cutout or temperature regulator with a fuse. Types A3B, A3LB, A3AB, AKB and A3KB are thermal limiters (with manual reset). The thermal response system operates by means of a bimetal snapdisc acting on a switch contact without any electrical connection. The system is insensitive to current, and reacts to external thermal influences. Plastic housing, base-plate and mounting lug are all voltage-free. Heat transfer is effected directly through the plastic/metal housing or solid media, and indirectly by convection, radiation and conduction in the case of gaseous media.
