Product details

Trip Class 10 means it will trip within 10 seconds at 7.2× the set current — standard for general-purpose motor starting where acceleration times are under 10 seconds. The IP20 front protection and 100 % relative humidity rating make it suitable for enclosed panels in washdown or high-humidity environments, though the relay body itself is not rated for direct spray. ATEX certification (DMT 98 ATEX G 001) confirms it meets the essential health and safety requirements for equipment in potentially explosive atmospheres.

Mounting and integration — contactor mounting, no extra DIN rail

Mounts directly onto the S00 contactor via the fastening method, saving a DIN rail position. The mounting position allows ±135° rotation and ±45° tilt forward/backward, so it adapts to tight enclosure layouts without special brackets. Clearance needs: 0 mm upwards, forwards, backwards, and downwards — the side clearance is 6 mm to adjacent devices for heat dissipation. Wire termination accepts 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²) solid or finely stranded with ferrule, plus AWG equivalents. Auxiliary and control circuits use the same screw-type terminals.

Frequently asked questions

What is the depth of this overload relay?

78 mm, which matches the standard S00 contactor depth for direct mounting without protruding beyond the contactor body.

What wire sizes does the screw terminal accept?

Solid or finely stranded with ferrule: 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²), plus AWG equivalents. The auxiliary and control terminals use the same type.

Does this relay have ATEX certification?

Yes, ATEX certification DMT 98 ATEX G 001 is listed, covering use in potentially explosive gas atmospheres.
