GEWISS Breakers

In distribution boards, protection is only as good as the breaker behind the toggle. The lineup of GEWISS breakers covers everything from standard feeder protection to high‑capacity three‑phase systems — the kind of devices you rely on in both commercial and industrial settings. When I’ve been on site inspecting panels, I’ve seen how choosing the right breaker (and curve) avoids nuisance trips, overheated buses, and future back‑charges.

GEWISS Circuit Breakers — Compact Protection for Low‑Voltage Systems

The GEWISS circuit breakers range includes the 90 MCB family, covering single‑pole, two‑pole and three‑pole configurations. They handle over‑current and short‑circuit situations with breaking capacities from 6 kA up to 25 kA depending on model.
From field practice: in a small commercial board you’ll often find a GEWISS MT100 1P breaker (16 A, curve C, 1‑module) protecting lighting circuits. That consistency simplifies spares and reduces errors at service time.

GEWISS MCB Miniature Circuit Breakers — Standardised DIN‑Rail Modules

When you hear GEWISS MCB miniature circuit breakers, think of devices built for high‑density panel assembly: 17.5 mm or 18 mm module widths, snap‑on DIN‑rail mounting, clearly labeled trip curves. The MT range includes versions from 1 A up to 63 A for curves B, C and D.
Installers appreciate the spacing and label‑ease; panel builders like the common footprint and consistent manufacturer — that means fewer surprises when sharing spares or doing retrofits.

GEWISS Single‑Pole Breakers & Three‑Phase Breakers — Matching Load Architecture

It’s critical to align breaker type with your supply architecture. For example:

• A GEWISS single pole breaker (1P) works for controlling a phase in residential or simple circuits.
  
   
• A GEWISS three phase breaker (3P or 3P+N) is required in three‑phase feeders, machinery feeds or large motor protection.
  Technical sheets show a 3‑pole MT100 rated 40 A, curve C, with Icn 10 kA and Icu 20 kA for 400 V/230 V use.
  Choosing the correct pole configuration up front avoids future board modifications or asymmetric load issues.

GEWISS 6 kA & 10 kA Breakers — Rated Breaking Capacity for Protection

One of the key specs you’ll check is the breaker’s breaking (or interrupting) capacity. GEWISS lists models with 6 kA and 10 kA ratings appropriate to many commercial installations. For heavier installations, the range goes to 20–25 kA in the same footprint.
From experience: if you specify a breaker with too low a breaking capacity and a fault happens, you risk damage to the breaker, busbars or downstream equipment. That’s why procurement often emphasises “Icu rating” as much as “A rating”.

GEWISS DIN‑Rail Breakers — Modular Equipment for Efficient Panels

The phrase GEWISS DIN rail breakers emphasises the modular design philosophy: every breaker is made to mount on EN 60715/50022 rails, share common depth and labelling space, and integrate with other modular devices (RCDs, RCBOs, accessories).
Panel builders and integrators like this because layout, labeling, and spares become standardised across different board sizes — saving time during assembly,commissioning and maintenance.

Procurement and Wholesale Buying Considerations

When buying GEWISS breakers in bulk for large installations – e.g., distribution boards for multiple floors, new builds, or retrofits – buyers typically compare:

• Breaker rated current (A) and trip curve (B, C, D) to match load characteristics
• Breaking/interrupting capacity (6 kA, 10 kA, 20 kA) to match short‑circuit levels
• Pole configuration (1P, 2P, 3P, 3P+N) based on supply architecture
• Physical module width and compatibility with existing rail layout (important for spares and expansions)
• Stock availability and packaging units (boxes, bulk) – panel‑builders prefer consistent supply to avoid project delays
• Compatibility with other modular gear (busbars, accessories) – when everything is from the same brand and platform installation and maintenance simplify
