Noark Breakers

NOARK Circuit Breakers as Fundamental Protection

In electrical control and distribution systems, circuit breakers are far more than switches — they are the frontline defence. NOARK circuit breakers deliver branch-circuit protection, fault interruption, and selective coordination across miniature (MCB), moulded-case (MCCB) and DIN-rail modular formats. The B1H series covers ratings from 0.5 A to 32 A for miniature breakers
From a procurement perspective: you must check trip-curve (B, C or D), pole count (1P, 2P, 3P, 4P), breaking capacity (10 kA typical) and standard compliance (IEC/EN 60898-1 or UL 489). Overlooking these leads to under-protection or over-sizing — both expensive.

Modular Protection Units for Scalable Distribution

When panel space is limited but flexibility is required, DIN-rail modular devices become critical. NOARK’s modular protection units fit 18 mm per pole widths, support accessories (auxiliary contacts, shunt trips) and allow future expansion without rewiring the cabinet. 
Key decision-factors: mounting footprint (multiplying poles), spare-module availability, and part-number stability across product cycles — standardisation here simplifies maintenance.

Overload Protection and Single/Three-Pole Breakers

Protection isn’t just about short-circuit interrupts; overloads must be handled too. NOARK overload protection devices and breaker families (single-pole and three-pole) address both modes. Their compact breakers allow branch design with reliable overload response and selective fault clearing.
In practice: combining correct frame size with overload trip settings (e.g., for motor feeders) ensures longevity and fewer faults.

Compact Breakers by NOARK for Space-Constrained Panels

When panel real estate is premium — machine control cabins, retrofit boxes — space-efficient breakers are essential. NOARK compact breakers (such as the Ex9BH/BH series) support full protection in reduced widths (18 mm per pole) and still deliver rated breaking capacity of 10 kA
The result: you get full protection, maintain spares consistency and avoid oversized modules that waste panel space.

Specification Checklist for Control Panel Procurement

When building your BOM, always verify:

• Rated current (In) & breaking capacity (Icn): Use proper worst-case scenario values, not “just estimated”.
• Tripping curve & selective coordination: Ensure upstream vs downstream discrimination (B, C or D curve).
• Mounting format & footprint: DIN-rail (35 mm) vs flush panel mount; module width matters.
• Auxiliary functions & accessories: Shunt-trip, undervoltage release, signalling contacts.
• Spare parts strategy & product continuity: Use one breaker family to simplify future maintenance and spares.
  Skipping any of these often triggers redesigns, inconsistent spares or service delays.

Why Standardising on NOARK Delivers Value

Panel-builders and OEMs who standardise on NOARK breakers report fewer vendor variations, faster build cycles and simpler documentation. For example: using the same breaker family across multiple lines cuts training time, aligns spare parts and reduces error-rates in field replacement. The brand’s global warranty (five-year limited) adds a further layer of reliability.
