Protection of single-phase and DC current motors:

1 pole

2 pole

Mounting position:

ZB12, ZB32, ZB65, ZB150, Z5

Tripping characteristics

These tripping characteristics are mean values of the spread at 20 °C ambient temperature in a cold state.

They show the tripping times in relation to the response current. When the devices are at operational temperature the tripping time of the overload

relay drops to approx. 25% of the value shown. Specific characteristics for each individual setting range can be found in the manual on
