Standards

IEC/EN 60947‑1, IEC/EN 60947‑5‑1

The 3TH2 miniature contactor relays are suitable for use in any climate. The miniature contactor relays with screw terminals are finger-safe according to IECВ 60529.

The terminal designations comply with ENВ 50011.

Connections

The 3TH20 miniature contactor relays with four auxiliary contacts are available with SIGUT screw terminals, 6.3В mmВ x 0.8В mm flat connectors, and solder pin connections.

The miniature contactor relays with 6.3В mm x 0.8В mm flat connectors can be used in the plug-in base with solder pin connections for printed circuit boards. The miniature contactor relays are coded, and the plug-in base is codable in order to ensure non-interchangeability.

The 3TH22 miniature contactor relays with eight integrated contacts are available with screw terminals. The terminal designations comply with ENВ 50011.

Contact reliability

High contact stability at low voltages and currents, especially suitable for solid-state circuits with currents ≥ 1 mA at a voltage of ≥ 17 V.

3TH27 latched miniature contactor relays

The contactor coil and the coil of the release solenoid are both designed for uninterrupted duty.

RC elements, varistors diodes or diode assemblies can be fitted to both coils from the front for damping opening surges in the coil.

The miniature contactor relay can also be switched on and released manually.
