Power Relays

HEAVY DUTY
SERIES 175 - OPEN TYPE 60 Amps
SERIES 185 - OPEN TYPE 100 Amps

Recent advancements in Electrical Contact Technologies have resulted in development of Heavy Duty High Current Relays - giving advantage over Hefty Electrical Contractors specially at places needing one or two Changeover Contacts .

The Self wiping action in contacts is introduced by specially spring loaded Electrical Contact Holding arms that result in longer contact life. Available in Open & Enclosed versions - but open versions are much more liberal in contact ratings, better lives and easy to maintain.

They are finding increased usage in Generator Changeover Panels, Automatic Lighting Switches, Motor Starting applications, Twi Light Switches, Automatic Phase Selector Switches. HEAVY DUTY SILVER CADMIUM CONTACTSranging from 8 to 16 mm diameters provide non welding contacts in even Inductive & Capacitive loads.

ONE OF THE LARGEST MANUFACTURERS OF RELAYS IN THE COUNTRY - in the range 0.5 A to 202 Amps - 72 Models.

Superior Heavy Duty Contacts now made available by the Contact manufacturers have resulted in development of HEAVY DUTY POWER RELAYS of 60 & 100 Amps. Capacities & of long life & high reliability.
Series 175 - OPEN TYPE 60 Amps
Series 185 - OPEN TYPE 100 Amps
Suffix 'A' Indicates AC relay e.g. 175 etc.
Features and Dimensions
» High quality, heavy duty power relay    designed for use in high current    applications such as motor starting &    incandescent lamp loads.
» Wide range of contacts arrangements    as SPST - Heavy Duty & SPDT - Light    Duty.
» Floating movable contact carrier    provides excellent pressure and wipe    between contact surfaces, thus    minimizing voltage drop across contacts    during life.
» Heavy 'moulded' Phenolic base &    stronger terminal support reduce risk of    breakages & is less amenable to    disturbance during usage.
» Superior design with built-in pressure     balancing arrangement & Screw     Controls for adjustment of Relay     Parameters.
» Since the company is engaged in    continuous development of the    products, the right is reserved to supply    the goods which vary from the    published data.
