Supu TPD double-deck spring terminal block adopts Push-in direct connection technology, enabling fast on-site wiring without auxiliary tools. It delivers excellent vibration resistance and supports maintenance-free long-term operation. Built on all core advantages of the TP series, TPD features a double-layer structure to achieve higher wiring density within limited installation space, with a maximum conductor size of 4mm² to fully meet current transmission needs of various equipment.
- Covers TPD1.5, TPD2.5, TPD4 wiring and grounding terminals, with a conductor range of 0.2–4mm² to fit diverse cable specifications.
- Tool-free operation: press the auxiliary button to insert/remove solid conductors and ferruled stranded conductors, enabling efficient on-site wiring.
- Available in double-deck 2-channel and 3-channel configurations for compact installation scenarios to maximize cabinet space utilization; the 1-pin-1-wire double-deck terminal can be paired with plugs for flexible wiring.
- Conductive TPD type supports electrical connection between upper and lower layers for inter-layer current transmission to fit varied current connection needs. Non-conductive TPD type has independent upper/lower circuits for separate cross-wiring, with labeled entry ports for easy on-site identification and operation.
With reliable spring-clamp vibration resistance, compact footprint and standardized DIN rail mounting, the series is widely used in demanding scenarios including rail transit onboard control systems, industrial automation line control cabinets, elevator drive control units, new energy power storage and low-voltage distribution equipment, providing high-density, high-stability wiring solutions for multi-industry electrical control systems.
