GHISALBA GH15 four pole contactors, available from NHP , are compact and offer contact configurations of 2 NO and 2 NC; 4 NO; or 4 NC for specialised applications.
GH15 contactors are reliable and offer a long electrical life that makes them suitable for emergency or general lighting systems, heating systems, four pole isolation of high impedance-earthed networks, changeover contactors, and pole changing motors with separate windings.
The contactors are available up to 125 amps ac1 at 55ºC, or 95 amps ac3. With a common range of accessories, GH15 contactors are available in a wide range of ac and dc coil voltages.
Further to the GH15 range, Ghisalba has 3-pole contactors up to 700kW that can be fitted with an additional pole for applications requiring four normally open contacts.
