BS EN 61095:2009 Electromechanical contactors for household and similar purposes

BS EN 61095 applies to electromechanical air break contactors for household and similar purposes provided with main contacts intended to be connected to circuits the rated voltage of which does not exceed 440 V a.c. (between phases) with rated operational currents less than or equal to 63 A for utilization category AC-7a and 32 A for utilization categories AC-7b and AC-7c, and rated conditional short-circuit current less than or equal to 6 kA.

The contactors dealt with in BS EN 61095 are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection should form part of the installation.

BS EN 61095 does not apply to

  • Contactors complying with BS IEC 60947-4-1
  • Semiconductor contactors
  • Contactors designed for special applications
  • Auxiliary contacts of contactors. These are dealt with in BS IEC 60947-5-1.

BS EN 61095 covers:

1) The characteristics of contactors.
2) The conditions with which contactors shall comply with reference to:
a) Their operation and behaviour;
b) Their dielectric properties;
c) The degrees of protection provided by their enclosures, where applicable;
d) Their construction;
e) Their electromagnetic compatibility characteristics.
3) The tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests.
4) The test sequences and the number of samples.
5) The information to be given with contactors or in the manufacturer's literature.
