Detailed introduction

Main purpose and scope of application
ZUM1 series plastic case circuit breaker (hereinafter referred to as circuit breaker) is one of the new circuit breakers designed and developed by our company comprehensively adopting international advanced technology.
The circuit breaker has a rated insulation voltage up to 690V (500V for type 63), suitable for AC 50Hz or 60Hz, rated operating voltage up to 690V, and rated operating current from 6A to 1250A. It is used to distribute electrical energy and protect circuits and The power supply equipment is protected from damages such as overload, short circuit, under voltage and other faults. At the same time, it can also be used as the motor's infrequent starting and overload, short circuit, and undervoltage protection.
The circuit breaker has the characteristics of small size, high breaking, short arcing (or no arcing), etc., which is an ideal product for users. The circuit breaker is installed vertically (ie vertical installation) or horizontally (horizontal installation).
With isolation function.
In this series, the third-grade products with shell frame grades ranging from 63A to 225A also have a transparent cover, so that customers can observe the internal operation of the product at any time. This product complies with: National Standard GB14048.2.

Model and meaning

Note*: The neutral pole (N pole) of the four-level product is divided into four types of
A-type N-pole, no overcurrent tripping element is installed, and the N-pole is always on, not combined with other three-level;
B-type N-pole No overcurrent trip element is installed, and the N pole is combined with other three levels (N pole is closed first and then opened);
C-type N pole is installed with overcurrent trip element, and the N pole is combined with other three levels (N The pole is closed first and then opened);
D-type N pole is installed with an overcurrent trip element, and the N pole is always on, and does not open and close together with other three levels;

Working conditions
1. The upper limit of ambient air temperature is +40℃, the lower limit is -5℃, and the average value of 24h does not exceed +35℃.
2. Altitude: The altitude of the installation site does not exceed 2000m.
3. Relative humidity: the relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40℃, and it can have a higher relative humidity at a lower temperature; the monthly average maximum relative humidity of the wettest month is 90%, and the The monthly average minimum temperature of the month is +25°C, taking into account the condensation on the surface of the product due to temperature changes.
4. Pollution degree: Pollution degree is 3

Ordering instructions
When ordering, users use the ordering code to place an order. The ordering code is composed as follows:
product model + internal accessory code (specify the rated working voltage for shunt and undervoltage) + do not write for power distribution, and add Z + electric operation for motor protection (P), Handle Z (no time writing) + internal accessory rated voltage code (no time, use 00).
For example, order ZUMl-100L, 50A, three-level, motor protection, shunt release (AC230V), electric operating mechanism (AC230V), and the number is 10 units. The order code is ZUM1-100/3310 (AC230V) ZP (AC230V).
