ParametersFrame current: 80/125/250/630; Usage category: AC-33iB (16A~630A); AC-33B (16A~350A); Pole number: 2P/3P/4P; Wiring method: Same side input, two in one out; Controller type: A (Standard type), B (Intelligent type)Advantages/Core Features01 Flexible and convenient; all series use the same side wiring design, saving 20% in material costs and improving wiring efficiency by 30%; using a new technology platform, the 80 frame size is reduced by 60%, and the 125/250 frame size is reduced by 30%, greatly saving cabinet space; 02 Safe and reliable; the switch uses a three-stage pre-energy storage design, with contacts capable of opening/closing within 10ms, and the contact switching speed is independent of manual operation, resulting in a longer product life and safer operation; the 125~630 frame size features humanized anti-misassembly design and small-angle mechanism design; manual operation is not possible in automatic mode, ensuring user safety; 03 Excellent performance; using a flexible rotating contact system, the usage category is up to AC-33B, which can cope with motor load or high inductive load current impact, expanding the application scenarios; it has functions such as over-voltage/under-voltage, fire protection, grid-generator, and can be flexibly configured according to different needs.

Product details

Function and Purpose

Same-side wiring, compact size;

Detailed Description

Parameters:
Frame Current: 80/125/250/630
Usage Category: AC-33iB (16A~630A); AC-33B (16A~350A)
Pole Number: 2P/3P/4P
Wiring Method: Same-side wiring, two in one out
Controller Type: A (Standard Type), B (Intelligent Type)

Advantages/Core Features:
01 Flexible and Convenient
All series use same-side wiring design, saving 20% material cost and improving wiring efficiency by 30%

Using a new technology platform, the 80 frame size is reduced by 60%, and the 125/250 frame size is reduced by 30%, greatly saving cabinet space
02 Safe and Reliable
The switch uses a three-stage pre-energy storage design, achieving opening and closing within 10ms, and the contact switching speed is independent of manual operation, resulting in longer product life and safer operation

125~630 frame uses humanized anti-mistake design and small-angle mechanism design; manual operation is not possible in automatic mode, ensuring user safety
03 Excellent Performance
Adopting a flexible rotating contact system, the highest usage category is AC-33B, which can cope with motor load or high inductive load current impact, expanding the application scenarios

It has functions such as over-voltage, under-voltage, fire protection, grid-generator, etc., and can be flexibly configured according to different needs
