YDC-P 1500V DC Contactor | 20A–400A 24V Coil Energy Storage Relay
YDC-P 1500V DC Contactor | 20A–400A 24V Coil Energy Storage Relay
The YDC‑P sealed high‑voltage DC contactor product line delivers graded continuous current ratings spanning 20A up to 400A, all rated for a system voltage of 1500 VDC with a standard 24V DC actuation coil. Every unit adopts reinforced magnetic DC arc suppression, thick low‑resistance copper bolt terminals and an IP54 dust‑proof splash‑proof flame retardant enclosure. The broad current portfolio covers small auxiliary circuit control up to heavy‑duty main busbar switching for utility photovoltaic arrays, container battery energy storage cabinets, commercial EV charging infrastructure and off‑grid lithium battery microgrids.

1. Product Overview
YDC‑P is a scalable series of premium magnetic DC contactors purpose‑built for 1500V class modern new‑energy projects. The segmented current lineup from 20A through 400A unifies shared platform design standards including magnetic arc extinguishing hardware, sealed rugged housing and industry‑standard 24V control coils, letting specifiers select exact amperage ratings for branch auxiliary loops all the way up to plant‑scale main power busbars.
All variants include vibration‑resistant base mounting lugs and traceable QR product labeling. The modular platform shortens project procurement workflows, simplifies spare‑parts stocking and maintains consistent long‑term reliability across rooftop solar, utility ground‑mount PV, grid‑scale battery storage, EV charging stations and heavy industrial battery backup systems.
2. Core Product Features
1. Full segmented current selection: 20A – 400A
- 20A ~ 63A: Auxiliary control loops, small solar string branch isolation, low‑power battery accessory switching
- 80A ~ 200A: Mid‑size combiner trunk lines, distributed commercial energy storage branch circuits
- 250A ~ 400A: Central main busbar disconnect for utility solar farms, large containerized battery storage stations
2. 1500VDC high‑voltage rated insulation system
3. Universal reinforced magnetic DC arc quenching
4. Current‑scaled solid copper bolt terminals
- Lower amperage units use compact machined copper lugs optimized for smaller cable gauges
- High‑current 250A–400A variants feature oversized copper terminals to suppress temperature rise under peak continuous loading
Anti‑oxidation plating resists corrosion inside humid battery cabinet environments; bolted connection hardware stays fastened reliably under recurring site mechanical vibration.
5. Consistent IP54 sealed flame‑retardant enclosure across the lineup
- Blocks battery electrolyte mist, cabinet dust and ambient humidity from eroding internal silver alloy switching contacts
- Flame retardant material curbs fire propagation in the event of abnormal internal arcing faults
- Molded structural reinforcement improves shock tolerance for mobile transportable battery storage container deployments
6. Standardized mounting & traceability features
- Uniform base lug hole patterns across all sizes simplify shared cabinet bracket design for multi‑rating project layouts
- Unique unit QR coding on every product sticker unlocks batch manufacturing logs, certification records and warranty tracking for commercial EPC project asset management
3. Working Conditions
- Maximum main circuit working voltage: 1500 Volts DC
- Unified coil control voltage: 24 VDC
- Ambient operational temperature band: -20℃ ~ +70℃
- Enclosure ingress protection rating: IP54
- Valid altitude operating ceiling: stable rated performance below 2000 m elevation
- Humidity operating cap: ≤90% non‑condensing relative humidity
- Deployment restrictions: avoid permanent water submersion and continuous contact with highly corrosive industrial gaseous agents
