Why every PV and battery storage system needs a disconnector.⚡

A disconnector isn't a circuit breaker. Under IEC 60947-3, its job is safe isolation — cutting a circuit from the supply so engineers can maintain inverters, combiner boxes, and battery racks with zero risk of energization. It's the switch you trust with your life during maintenance.

The specs matter when you scale:

• Current range spans 100x — from 40 A residential strings to 4000 A utility-scale feeders
• Voltage coverage up to AC 1140 V and DC 1000 V
• Breaking capacity up to 220 kA
• Pole configurations from 2P to 8P

Disconnectors on QuiSure cover it all:

✅ One sourcing platform: 23 AC series + 17 DC series
✅ AC/DC universal family: 40–1250 A, up to 1000 V AC/DC
✅ High-current options: up to 4000 A, 1140 V AC
✅ DC-rated options for PV and storage: up to 1000 V DC

One platform. Full isolation coverage.

🚗⚡️ Electrical Protection & Switching for DC Fast Charging Stations

High-power DC charging places extreme performance demands on switching and protection components. Here is how an optimized AC/DC portfolio solves critical field challenges:

⚠️ Application Pain Points:
▪️ DC contactors face contact burning under DC 1000V (1,000-cycle life req.) and high temp rise from circuit harmonics.
▪️ Downstream wiring on residual current MCCBs drives up copper busbar costs.

💡 Solution Value:
✔️ Strong Anti-Burning Contacts: Minimizes failure risks during high-power, long-duration charging.
✔️ Lower Temp Rise (50K): Extends lifetime and boosts reliability in high-temp and high-altitude setups.
✔️ Cost-Effective Downstream Wiring: Reduces copper busbar usage while maintaining 100% breaking capacity without derating.

🛠️ Featured Component Specifications:
▪️ 50A DC Contactor: 50A | Up to DC1000V | Coil: DC12V/24V/48V
▪️ 120A DC Contactor: 120A | Ui: DC1000V | Coil: DC12V/24V | Compact design
▪️ Residual Current MCCB: 225A–400A | AC380V–415V | 3P/4P | Icu: 70kA
▪️ Standard AC MCCB: 225A–400A | Up to AC690V | 3P/4P | Icu: 20kA–100kA
▪️ 170A AC Contactor: 170A | Up to AC690V | 3P | Wide AC coil selection
▪️ Type 1+2 PV SPD: Uc: 1300V DC | Iimp: 6.25 kA | Imax: 40 kA | Up ≤ 4.0 kV

A 5G base station cabinet is about the size of a fridge. Inside it: breakers, SPDs, monitoring modules — all crammed into a few centimeters of rail.

You can't just swap the cabinet when you need more capacity. So the components have to do more in the same space.

The MB8Z-63 is an intelligent 1U MCB rated up to 63A at DC60/80V for telecom. It handles overcurrent protection like any breaker, but it also talks — RS485 gives you real-time voltage, current, power, energy, and temperature data, plus remote control, telemetry, signaling, and adjustment. Need more current? The MB8Z-125 goes up to 125A with the same feature set.

Pair it with the VPM385-40 1U SPD: Type 2, Imax 40kA, pluggable module for easy replacement. Same 1U footprint, same rack, remote fault signaling built in.

One rack unit. Overcurrent protection that reports back, surge protection that's easy to maintain. That's the kind of density 5G cabinets actually need.

What's your biggest space headache in cabinet design?
