Eaton Contactor Overload Relay – ZB Series Thermal Overload Relays


The Eaton ZB series thermal overload relay with direct contactor mounting offers reliable motor protection and control in the event of a single-phase failure or overload within a multitude of environments. The auxiliary contacts disconnect the contactor and signal the fault when it overloads, meaning a reset can then take place. It works by cutting off the current to the motor when a high current situation occurs. As the relay receives the corresponding signal, it trips.

This Eaton product is predominantly designed for imitating the heating prototypes that are a staple for keeping your motor circuits healthy, which increases the motor lifetime. It provides an affordable and efficient way for you to protect your motors, whilst giving you peace of mind that you have sufficient motor protection and control.

Eaton’s ZB series overload relays offer reliable and high-quality electric motor control within a multitude of automation and control environments. The ZB series overload relays come with a 500 V ac control voltage, a contact voltage rating of up to 1000 V ac, a temperature range of -5 to +55 °C and 2 auxiliary contact points. Eaton offer a wide range of reliable contactor overload relays to protect machinery from overheating, keeping your business and its operations accessible. All Eaton ZB thermal overload relays can also be used for protecting EEx e motors whilst being an effective and sustainable way for you to protect your motors.

Features and Benefits


• Protects equipment against phase failure or electrical overload.

• Short circuit protection when fitted directly to a contact.

• Modular relay design for use with the DILM contactor range

• 1NO/1NC Auxiliary contacts

• Bimetallic tripping mechanism with trip response from 2 to 10 seconds

• Suitable for protection of Atex motors.

• Single phase failure sensitivity to IEC/EN 60947.

• Manual and automatic reset options.

• Class 10 A overload

When fitting overload relay remote from contactor or using more than one overload relay, use remote mounting base (stock no. 493-0488 - ZB32 only, stock no. 513-0336 - ZB65 only). Note: ZB12 have 5 pins, ZB32 have 4 pins.
