Frequently Asked Questions

What capacities are available?

The GEYA GBHL and GBBL series alloy distribution box is available in nine distinct capacity specifications ranging from 12P up to 72P, allowing electrical contractors to securely house between 12 and 72 standard 18mm DIN-rail modules for extensive low-voltage circuit branching. This flexibility ensures compatibility with various project scales.

Difference between GBHL and GBBL?

The primary distinction between the two models lies in the front panel material, with the GBHL featuring a durable alloy panel and the GBBL utilizing a scratch-resistant tempered glass panel, while both share the same powder-coated cold-rolled steel enclosure and internal wiring configurations. Both options offer excellent aesthetic integration.

Does it include busbars?

Yes, every unit comes standard with a pre-installed 35mm by 1.0mm thick DIN rail and a dual copper busbar assembly that includes a neutral bar positioned at the top and a ground bar at the bottom for highly efficient and secure wiring. This optimized structure significantly reduces installation time.

What are the installation precautions?

Installation must strictly be executed by a certified electrician who ensures the main power supply is entirely disconnected before wiring, and moreover, there must absolutely be a zero position to retain a forced power-off operating environment for maximum safety during maintenance. Verify proper wall depth for flush mounting applications.
