This compact busbar mounted contactor follows the recognised design of the SW150 series of contactors and is devised for uninterrupted loads. They are primarily for use with direct current loads but can be used for alternating current loads. • Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact résistance). The SW140 features single pole double breaking main contacts with silver alloy tips which are weld resistant, hard wearing and have excellent conductivity. Mounting can either be horizontal or vertical. The SW140 is easy to install, with "L" Shape Mounting bracket kits fitted as a standard option, or alternatively the M4 tapped holes Application Uninterrupted Thermal Current Rating (^h) 140A à Intermittent Current Rating: à 30% Duty 255A à 40% Duty 220A à 50% Duty 200A 60% Duty 180A à 70% Duty 165A A Rated Fault Current Breaking Capacity ('cn) Resistive Load*: SW140 210A at 60V D.C. à Maximum Recommended Contact Voltages (Ue): SW140 60V D.C. à Typical Voltage Drop per pole across New Contacts at 100A < 40mV A Mechanical M.T.B.F >1 x 106 A Coil Voltage Available (Us) From 6 to 240V D.C. ^ Coil Power Dissipation: Intermittently Rated types 15 - 20 Watts à Continuously Rated Types 7 - 13 Watts à Maximum Pull-In Voltage (Coil at 20° C) Guideline: Intermittently Rated types (Max 70% Duty Cycle) 60% Us À Continuously Rated Types (100% Duty Cycle) 66% Us à Drop-Out Voltage Range 10 - 25% à Typical Pull-In Time 15ms à Typical Drop-Out Time (N/O Contacts to Open): ^ Without Suppression 5ms à With Diode Suppression 50ms à With Diode and Resistor (subject to résistance value) 8 - 20ms à Typical Contact Bounce Period < 5ms à Operating Ambient Temperature - 40°C to + 60°C à Guideline Contactor Weight: à SW140 440 gms à With Auxiliary + 20 gms A Auxiliary Details Auxiliary Thermal Current Rating 5A à Auxiliary contact switching capacities (Resistive Load): 5A at 24V D.C. à 2A at 48V D.C.
