Vinayak Controls is a firm having more than 3 decades of experience in marketing and distribution of switches to Switch gear, Relay Control Panel, Railways, Telecom, Electricity boards and Cement Industries.

Switron Control switches are cam operated switches which are ideal for use in industrial applications like Tripping and closing operations of circuits breaker for local–Remote /auto-manual selection of breaker operations. The versatile design of these switches enables infinite switching combinations. Switron Control switches are manually operated and robust in design incorporating double break butt contacts.

Specification:

Switron Control switches comply with IS-6875 Part I, II, III, 1983 for utilization categories DC II and AC II. As motor control applications switches comply with IS 4046 part I & II AC3 category.

Electrical Data:

• Thermal Current: 40A

• Continuous Current: 32A

• Operational Voltage DC/AC: 660Volts.

• High Voltage Test: 2.5 KV (R.M.S).

• Ambient Temperature: 55^oC

• Frequency of Operations: 300 cycles/hour

• Mechanical life: 1 Million Operations.

• Electrical life (AC inductive): 2.5lakh Operations.

• Short Time Withstand Current: 384A. for 1 Sec

• Short Circuit Making Capacity: 542A

DC breaking capacity of each contact 2.5A at 250V DC L/R-20 M Sec.

DC breaking capacity can be increased by using multiple series contacts for specific applications.

BREAKER CONTROL SWITCHES

Breaker control switches are essentially spring return switches having spring return from either sides of neutral position at 45^o, other switching angles such as 30^o, 60^o, 90^o can be provided on request. These switches can be provided with following features.

a) Lost Motion Contacts (NAT & NAC):

In addition to main breaker contacts, lost motion contacts can be provided at rear side of switch which indicate last operated position of breaker. These contacts are also known as Bell Alarm contacts. Any number of such NAC & NAT contacts can be provided.

b) Sequence Locking Device:

This is a mechanical device incorporated in the spring return switch which prevents any two successive operations generally successive closing operations are prevented, keeping trip free.

c) Centre Key Lock:

To prevent unauthorized operation of the switch, center key lock can be provided on the top switch. It is lockable only in four positions at 90^o (0^o, 90^o, 180^o, 270^o) and also at -45^o, +45^o.

Two varieties of locks available:-

• Lever lock (L).

• Tee type or knob type lock (T).
