Model implicatio

BQC Explosion Proof Magnetic Starter

Note: 1. please selection according to the control of the motor power, reference pagedown form related parameter choice;

2. integrated magnetic products with high internal fault miniature circuit breaker,

there is the requirement in the order, please indicate the type,

3. “setting current” by the compatibility of thermal relay setting current regulation scope, please specify when ordering. if Does not indicate the product according to the default value setting.

Example: 1. if you need to order dust explosion magnetic starter, was charged with motor power in 7.5kW~11kW, between Ask for motor to realize positive & negatuve control, the order type   BQC-Extd-25/N   ;

2. if you need to order explosion magnetic starter, was charged with motor power in 15kW~18.5kW, requirements between products Own circuit breaker, the order type   BQC-G40(   B)
