Eaton ZB32-1.6 tepelné nadprúdové relé 1,0-1,6 A pre DILM17-32 stýkače 278447

Industrial electricians and panel builders use the Eaton ZB32-1.6 thermal overload relay to protect three-phase motors up to 1.6 A from overheating and phase failure. It mounts directly onto DILM17, DILM25, or DILM32 contactors, forming a compact motor starter combination for machine tools, conveyors, and pumps.

Key specifications

• Adjustable current setting range: 1.0 – 1.6 A
• Overload release class: 10A
• 3-pole main circuit with 1 NO + 1 NC auxiliary contacts
• Manual/automatic reset selectable
• Rated operational voltage up to 690 V AC
• Screw terminals, IP20 protection
• Operating temperature: -25 to +55 °C

Why choose it

The ZB32-1.6 provides reliable thermal protection with phase-loss sensitivity, ensuring motors are disconnected before insulation damage occurs. Its direct mounting to Eaton DILM contactors saves wiring time and panel space. The selectable reset function allows either manual intervention after a trip or automatic restart for unattended operation.

Ideal use cases

• Protecting small three-phase motors in industrial machinery
• Motor starter combinations with Eaton DILM17-32 contactors
• Applications requiring precise overload setting between 1.0 and 1.6 A

Good to know

The relay conforms to IEC/EN 60947-4-1 and VDE 0660 standards. It is designed for screw terminal connection and operates within an ambient temperature range of -25 to +55 °C.
