LOCKOUT RELAY SWITCH

B-MR type
B-MR
LOCKOUT RELAY SWITCH

B-MR type (Solenoid type)

Description

Lockout relay is used to control and protection such as power generation and distribution
equipment.

It's possible to judge the state of the Lockout Relay from the target color.

The operation time realized shorter by adopting a solenoid coil. Quick response protects other
instruments from malfunction.

Features

1. High Speed Operation

Operation time becomes less than 16ms including bounce.
~Operation time~
NC Contact : Less than 8ms, NO Contact : Less than 8ms

2. Compact size
The mechanical portion of solenoid type is smaller than BA-6 Coil type.

3. Wide variation of coil

There are 10 types of coils, each type differs operation time and also preparing BA-6 Coil type

various operation voltage.

A-G : High speed operation type (NC contact operation time will be less than 8ms.)
H-J : Normal operation type (NC contact operation time will be less than 30ms.)

～Remarks～
*Operation time is varied depending on the handle type.
*NC contact operation time will be 30ms.
*Operation time differs from handle type and circuit voltage.

PRECAUTIONS FOR USE

• Use products within the correct voltage and current.
• Check connections carefully, as a faulty connection may lead to accidents.
• Check for no abnormal conditions such as wire break, etc. before using the products.
• Fasten screws by the torque complying the standard.
• Use products under no stress condition to wires.
• Avoid the excessive shock and vibration.
• Use under the conditions of no organic solvent or oil.
• Avoid using products in abnormal environments such as high temperature, high humidity, dust or corrosive gases.
• Check carefully specification when used for special purpose.
