IEC EN 60947-5-1 Low Voltage Switchgear and Control Equipment - Part 5-1: Electromechanical Control Circuit Devices Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60947-5-1 test. IEC EN 60947-5-1 covers control, signaling, interlocking, etc. of switchgear and control gear. It applies to control circuit devices and switching elements intended for Applies to control circuit devices whose rated voltage does not exceed 1000 V ac (at a frequency not exceeding 1000 Hz) or 600 V dc.

This standard applies to certain types of control circuit devices such as:

• Manual control switches, such as push buttons, rotary switches, foot pedals, etc.;
• Time-delayed or momentary electromagnetically actuated control switches, eg contactor relays;
• Pilot switches, eg pressure switches, temperature sensitive switches (thermostats), programmers, etc.;
• Position switches, such as control switches operated by a machine or part of a mechanism;
• Related control circuit equipment, such as indicator lamps, etc.

It also applies to certain types of switching elements associated with other devices (whose main circuits are covered by other standards), for example:

• Auxiliary contacts of a switching device (eg contactor, circuit breaker, etc.) that are not intended to be used solely with the coil of that device;
• Envelope door lock contacts;
• Rotary switch control circuit contacts;
• Overload relay control circuit contacts.

Auxiliary contactors meet the requirements and tests of IEC EN 60947-4-1, apart from the usage category that meets this standard. This standard does not cover relays within the IEC EN 60255, IEC EN 61810 series or automatic electrical control devices for household and similar use.
