1. Security and protection integrated design, anti-parallel thyristor chips, with the features of big operating current, resist to surge and high reliability.
2. ASH-B Series 40A-150A load terminal voltage can be up to 660VAC, resistive load actual current can be up to 80% -90% of the rated current.
3. Unique strength copper power terminals, with more stability.
4. Full copper plate, compared with a variety of aluminum plate and zinc plate, improves the product performance of pressure drop and heat dissipation, to ensure long life product.
5. Premium grade flame retardant nylon plastic, high temperature resistant can be up to 150-200℃; Compared to white BBS plastic case SSR, its temperature is just 70-80℃. Wiring shield can be opened, so increase operational safety.
Note 1. Model selection method: calculate the load current, according to load type, multiply the balance factor.
Resistive load: balance factor is 2 times, such as incandescent lamp, resistance wire, oven, heating rod.
Inductive load: balance factor is 7 times, such as: transformer, coil, fan motor, pump motor.
Example: 220V 3KW resistive load. 3KW/220V*2=27.3, select 40A specification.

2. To use product long and safely, please install the product with corresponding heat sink and fan.
