What the product is

Hager ADA316G is a 1P electronic RCBO designed to combine overcurrent protection and 30mA residual current protection in one modular device. For this exact SKU, Hager verifies a rated current of 16A, a B curve trip characteristic, Type A residual current detection, a 6kA short-circuit breaking capacity and a one-module format for DIN rail installation. Rated operational voltage is 230V, rated insulation voltage is 250V and rated impulse withstand voltage is 4kV.

ADA316G belongs to Hager's reduced-height ADA RCBO family. The most important buying point is the current rating. ADA316G is the 16A member of the range, so it should be chosen where the circuit design specifically calls for 16A protection and not treated as interchangeable with nearby 10A, 20A, 25A or 32A versions.

Why the 16A variant matters

ADA316G exists for circuits that require a 16A protective device, and that exact rating is the real reason to buy this SKU. In a modular protective range, small differences in current rating are not cosmetic. They affect whether the device is correctly matched to the circuit being protected. ADA316G therefore needs to be specified against the circuit design and not selected as a broad substitute for another member of the family.

Type A residual current protection is another key specification. Hager identifies ADA316G as Type A, which means the device is intended to detect AC and pulsating DC residual currents. That makes the residual current type an active part of the buying decision rather than a hidden technical line item.

Technical standards and ratings

Hager identifies the ADA reduced-height RCBO range to BS EN 61009-1 and BS IEC 1009-2-2. Hager also states that the range supports compliance with BS 7671 requirements for 30mA additional protection, circuit segregation to minimise inconvenience in the event of a fault and protection of wiring concealed in walls when installed in a consumer unit. ADA316G also carries energy limitation class 3, 50Hz operation, 16,000 electrical endurance cycles and 20,000 mechanical operations.

Installation, fit and compatibility

ADA316G is intended for modular board installation on DIN rail. One-module width helps preserve space in the enclosure, while top and bottom screw terminals give a familiar termination layout. Hager verifies conductor capacity of 1 to 10 mm² flexible and 1 to 16 mm² rigid cable. Hager's residential distribution literature also places RCBOs like ADA316G within consumer units designed to accommodate RCBO outgoing ways, which helps locate the product within its wider system context.

Who this exact variant suits

ADA316G suits installers and buyers who need a verified 16A Type A RCBO for a single-phase final circuit and who want individual outgoing way protection rather than a grouped arrangement. It also suits projects where the compact one-module footprint helps keep board layout efficient without losing RCBO-level circuit separation.

Why buy this exact variant

Choose Hager ADA316G when the board schedule calls for a 16A B curve RCBO with 30mA Type A protection and 6kA breaking capacity. The buying value of this exact SKU is the combination of verified current rating, modular format, conductor capacity and Hager distribution board context. That makes it a sound choice for precise replacement work and properly specified new installations.

Warranty

Hager lists switchgear in its UK product warranty policy with a 2-year warranty period.
