What the product is

Hager ADA310G is a 1P electronic RCBO designed to provide both overcurrent protection and 30mA residual current protection in one modular device. For this exact SKU, Hager verifies a rated current of 10A, 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.

ADA310G sits within Hager's reduced-height ADA RCBO family. That family point matters because the buying decision is not just about choosing any 30mA RCBO. The current rating is the real differentiator between close variants. ADA310G is the 10A version, so it should be selected only where the circuit design and board schedule call for 10A protection rather than a higher-rated device from the same range.

Why the 10A variant matters

ADA310G is the 10A member of the family, and that is the main reason to choose it instead of another ADA model. Protective device selection is driven by the circuit design, not by a broad description such as single-module RCBO. A 10A RCBO is used where the outgoing way has been designed and specified for 10A protection. That makes exact current rating accuracy more important than any generic family wording.

Type A residual current protection is also a meaningful distinction. Hager identifies ADA310G as a Type A device, intended to detect AC and pulsating DC residual currents. For buyers comparing older or more basic products, that matters because Type A protection should be explicit and not assumed from the family name alone.

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 provisions covering 30mA additional protection, circuit segregation to reduce inconvenience in the event of a fault and protection of concealed wiring when installed in a consumer unit. ADA310G also carries energy limitation class 3, 50Hz operation, 16,000 electrical endurance cycles and 20,000 mechanical operations.

Installation, fit and compatibility

ADA310G is built for modular board installation. One-module width helps conserve DIN rail space, while top and bottom screw terminals provide a familiar termination arrangement. Hager verifies conductor capacity of 1 to 10 mm² for flexible cable and 1 to 16 mm² for rigid cable, which is useful when matching the outgoing conductor and enclosure layout. Hager's residential distribution literature also places RCBOs like ADA310G within consumer units designed to accommodate RCBO outgoing ways.

Who this exact variant suits

ADA310G suits installers and buyers who need a verified 10A Type A RCBO for a single-phase final circuit and do not want to substitute a different current rating. It is appropriate where individual RCBO protection is preferred in place of shared RCD arrangements and where compact one-module format helps maximise available way space in the board.

Why buy this exact variant

Choose Hager ADA310G when the board schedule specifically calls for a 10A B curve RCBO with 30mA Type A protection and 6kA breaking capacity. The value of this exact SKU is the verified combination of current rating, residual current type, modular width, conductor capacity and Hager board compatibility context. That makes it a dependable choice for accurate replacement work and disciplined new-board assembly.
