In the power distribution design of distribution cabinets, automation complete sets, photovoltaic energy storage, and industrial control equipment, there is a common pain point: circuit breakers have limited outlet terminals. Multiple cables cannot be directly connected to the lower end of the air switch. Forced parallel wiring leads to messy wiring, uncontrollable torque, and potential safety hazards such as overheating and poor contact.
LINKWELL DBK series MCB/MCCB distribution terminals are an integrated branching solution developed for this power distribution challenge. Compatible with miniature circuit breakers (MCB) and moulded case circuit breakers (MCCB), they cover a full current range from 63A to 630A to meet branching requirements for different power levels.
The DBK series features an integrated incoming conductor structure for easy installation. It can be directly mounted at the lower end of matching circuit breakers without extra busbar adapters, saving valuable space inside cabinets. The terminals come with phase color markers in blue, green, brown, black, white, red and yellow for easy on-site identification of live wires, neutral wires and protective earth wires. Wiring is well-organized to reduce the risk of misconnection and simplify circuit inspection and maintenance later.
A wide range of specifications with various outlet configurations are available:
✅ DBK63 series (63A): 3-out, 4-out, 6-out, 9-out, suitable for low-current miniature circuit breakers, control circuits and small power circuits
✅ DBK125 series (125A): 3-out, 6-out, 9-out, widely used in medium and small-power complete cabinets
✅ DBK250 series (250A): 3-out, 6-out, 8-out, 9-out, compatible with medium-rated moulded case circuit breakers
✅ DBK400 series (400A): 5-out, 6-out, 9-out, 12-out, 18-out, for centralized multi-circuit branching
✅ DBK630 series (630A): 3-out, 5-out, 6-out, 9-out, 15-out, high-current main circuit multi-way shunting for high-power energy storage and industrial control main power distribution
Flexible cable size options are supported, ranging from small 2.5mm² conductors up to 50mm² large-section cables. One terminal realizes one-in multi-out shunting to replace traditional busbar parallel connections. Wiring is neat and standardized. Each circuit is independently clamped with stable torque, effectively reducing temperature rise at connection points.
Full series comes with complete safety certifications: CE, CB, TÜV, RoHS, IEC and UL94-V0 flame retardant rating, complying with IEC 60947-7-1. It satisfies compliance requirements for domestic complete-set projects and exported automation, photovoltaic and energy storage cabinets for the EU and overseas markets, with no extra concerns over certification matching.
