• Contact configuration: 1 normally open (1NO) and 1 normally closed (1NC)
• Compatibility: Zamel EXTA STM series contactors

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. Before beginning, ensure that the main power supply to the contactor is disconnected. The SPM-05-11 block is designed to be mounted directly onto the designated side of the EXTA STM contactor. Align the mounting clips with the contactor housing and press firmly until the unit clicks into place. Once secured, connect the control wires to the appropriate terminals according to your wiring diagram. Verify all connections for tightness before restoring power to the system.

What to consider before purchase

• Verify that your contactor is part of the EXTA STM series
• Ensure the 5A current rating is sufficient for your control circuit requirements
• Confirm that your control logic requires a 1NO+1NC configuration

Usage recommendations

Always perform a functional test of the auxiliary contact after installation to ensure that the feedback signal correctly reflects the state of the main contactor before putting the system into full operation.
