Product catalog summary
Overview: The document provides technical specifications and options for the SW60 series contactors by Albright International. These contactors are designed for applications requiring switching of resistive, capacitive, and inductive loads, such as small traction motors and hydraulic power packs.
Specifications:
  • Thermal Current Rating: 250A for interrupted and 350A for uninterrupted applications.
  • Intermittent Current Rating: Varies with duty cycle, e.g., 145A at 30% duty.
  • Fault Current Breaking Capacity: 400A at 48V D.C. for SW60 and 400A at 96V D.C. for SW60B.
  • Maximum Recommended Contact Voltages: 48V D.C. for SW60 and 96V D.C. for SW60B.
  • Coil Voltage Range: 6 to 130V D.C.
  • Operating Temperature: -40˚C to +60˚C.
Options and Features:
  • Auxiliary Contacts and Magnetic Blowouts available as options.
  • Environmentally protected to IP66 standards.
  • Mounting options include M4 tapped holes or brackets.
  • Single pole double breaking main contacts with silver alloy tips for durability and conductivity.
Performance Notes:
  • Performance data should be used as a guide; variations may occur based on application.
  • Thermal current ratings depend on conductor size.
  • Contact resistance increases with frequent switching under interrupted current conditions.

SW60 Single Pole Single Throw Normally Open-1

SW60 Single Pole Single Throw Normally Open (Part of the SW60 Series) Thermal Current Rating (Ith) Intermittent Current Rating: 30% Duty The SW60 is a miniature series single pole contactor - free standing and compact it is designed to fill the gap between 30 ampere relays and 100 ampere contactors. Devised for both interrupted and uninterrupted loads, the SW60 is suitable for switching Resistive, Capacitive and Inductive loads. Typical applications include switching small traction motors, hydraulic power packs and small electric winch motors. Rated Fault Current Breaking Capacity (Icn) 5ms Time Constant: (in accordance with UL583*) SW60 Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance). The SW60 features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW60 has M6 stud main terminals and 6.3mm spade coil connections. It can be mounted via M4 tapped holes or mounting brackets – either supplied fitted, or as separate items. Mounting can be on the side or base of the contactor.
