1000GH family — two variants for clear, reliable circuit protection 1000GH 315UL: includes a built-in fast-acting fuse for immediate overcurrent protection. 1000GH 400UL: standard version without an integrated fuse; use when external protection is preferred. Key benefits — why this solves your problems Immediate equipment protection: the 315UL’s fast-acting fuse trips quickly on overcurrent events, reducing risk of damage to power supplies, motor drivers, and sensitive control electronics. Simple maintenance and planning: distinct model IDs make it easy to identify which boards include integrated protection, speeding replacement and inventory management. Drop-in compatibility: both variants are compatible with standard 1000GH circuits and common control-board layouts, enabling straightforward swapping or upgrades without redesign. Space-conscious, dependable design: compact form factor and reliable construction fit tight control panels and development boards while standing up to typical automation use. Key attributes Function: overcurrent protection (315UL with built-in fast-acting fuse) or standard connector/component (400UL). Compatibility: designed for standard 1000GH circuits and typical control-board footprints for easy integration. Size: compact form factor suitable for confined panels and prototyping rigs. Construction and performance: reliable build quality intended for automation, control panels, and development environments; fast-acting fuse option provides rapid response to short-circuit or surge conditions. Practical use scenarios 1) Compact automation panel input protection — Install 1000GH 315UL at the power-supply input to limit fault damage and reduce downtime from wiring or module shorts. 2) Small motor-control or sensor systems — Use 315UL to protect motor drivers and sensor modules from overcurrent events during startup or fault conditions; choose 400UL when the system already uses a fused bus. 3) Prototyping and test benches — Fit 315UL to streamline safety during iterative testing and reduce the need for external fusing while validating designs. How to choose Select 1000GH 315UL when you want built-in, fast-acting overcurrent protection right on the component. Select 1000GH 400UL when you prefer a standard component without an integrated fuse, or if you will provide external overcurrent protection. Order the model that matches your protection strategy: built-in fast response (315UL) or standard component for external protection (400UL).
