Product Features

Adopting thermosetting plastic fully enclosed structure, it has high dielectric properties, protection ability and reliable operation safety.
The use of spring energy storage, instantaneous release of the accelerated closing mechanism and multi-breakpoint parallel contact structure greatly improves the electrical and mechanical properties of the product.
160A, 250A, 400A adopt modular design, 630A adopts integrated structure to ensure load operation and reliable short-circuit protection function.
Available in 3-pole and 4-pole (3-pole + switchable neutral pole).
The handle can be directly mounted on the switch for operation (referred to as in-cabinet operation), or it can be operated outside the distribution cabinet door through an extended shaft (referred to as out-cabinet operation).
Normally open and normally closed auxiliary contacts and rear panel wiring methods can be provided as required.

Frequently Asked Questions

What pole configurations are available for the HGLR series?

The HGLR switches are available in both 3-pole and 4-pole configurations (3-pole + switchable neutral pole) to suit different wiring and electrical layout demands.

Are fuses included in the standard sales price of the HGLR switch?

No, the sales price does not include fuses. Fuses need to be provided by the user separately depending on their system requirements.

Can the switch handle be operated from outside the distribution cabinet?

Yes. While the standard handle can be mounted directly on the switch for in-cabinet operation, you can also operate it outside the cabinet door using an extended shaft (out-cabinet operation).

What is the rated insulation voltage (Ui) for this range of switches?

The rated insulation voltage for the HGLR series switch is 800V across all model specifications.

How does the modular design benefit installation?

Models rated 160A, 250A, and 400A feature a modular design, while the 630A model employs an integrated structure. This ensures highly reliable load operation and optimal short-circuit protection.

What options exist for wiring and auxiliary contacts?

HGLR switches support both front panel wiring and wiring behind the board. Additionally, normally open and normally closed auxiliary contacts can be customized and provided based on your exact requirements.
