Ask anyone who builds control cabinets day after day — a breaker that trips too late or too early ruins your weekend. Murrelektronik breakers and DIN modular devices are made for people who don’t want to babysit their panels. They’re small, solid, and predictable. You mount them once, wire them right, and they keep working through heat, vibration, and dirty power.
The catalog covers thermal-magnetic breakers, electronic circuit protection for 24 V DC, and modular add-ons that link directly to busbars or power supplies. Every unit sits neatly on the DIN rail; the terminals lock with just the right tension. Current ranges run from 0.5 A to 32 A, with breaking capacity up to 10 kA — plenty for control cabinets and machine systems.
What Murrelektronik really nailed is electronic protection. Their MICO modules — small black and green units you’ve probably seen in any modern panel — isolate only the faulty circuit, not the whole power rail. Each channel has an adjustable threshold, LED indicator, and signal output to the PLC. When one channel overloads, it drops out cleanly, while the rest keep running. No random reboots, no full reset after a short.
Installers like them because you can build flexible power distribution blocks without external fuses. You decide the trip point per channel — 2 A, 4 A, 6 A — by simple switch. Once a fault clears, the channel resets automatically. It’s a small thing, but when you’re running 24 V DC loads with hundreds of sensors, that reliability saves hours.
The DIN modular form factor is another strong point. Whether it’s a classic breaker, power distribution unit, or an interface relay, the footprint stays the same — 35 mm rail, identical spacing, the same clear markings. That’s why cabinet builders prefer Murrelektronik: no improvisation, no cutting plastic, everything lines up cleanly.
You can mix thermal breakers for 230 V AC circuits with MICO electronic modules for the low-voltage side. Both share identical bus links, so your control and field power distribution look unified. These details separate industrial-grade systems from hobby-grade panels.
In factories, people remember what doesn’t break. That’s why Murrelektronik sticks. Electricians mention that screw torque stays stable even after years of vibration. The reset buttons don’t jam, the terminal markings don’t fade, and replacement modules click right in without rewiring.
One maintenance engineer once said it best: “We used to keep spare breakers for every brand. Now it’s just one box with Murrelektronik labels — fits everything we build.” That kind of consistency comes from good design, not marketing.
Bank of Lamps supplies the complete Murrelektronik breaker and modular protection range throughout Europe. Stock is maintained in Latvia for quick turnaround, with full traceability by EAN and MPN. Whether you order classic circuit breakers or MICO electronic protection, everything arrives from the same logistics stream — tested, documented, ready for installation.
