Name of product: Motor protection circuit breaker 3VU13

Mould No.: DZS7-25(3VU13)

Requirements and Usage:

1) Circuit requirements:

   Power Frequency: 50/60 Hz

   Rated current:0.16- 25A

2) Can be used as across the line starter

3) Overload or short circuit protection for motors

Summarize:

DZS7(3VU) series circuit breakers are compact circuit breaker whoes rated current can be up to 30 KW, 63A. They are working based on the principle of current limiting. They can be used for motor or other loading protection of starting, cutting, overloading and short-current.

Features:

(1)    When they are used as protecters of motor or equipment, ciircuit breakers aboved will all come with instantaneous releases and delayed releases.

(2)    The circuit breaker and the contactor can be assembled as a none fused starting apparatus.

(3)    When its rated working current is from 0.1A to 52A, it can not only be  used for motor protection of overloading, short-current and fhase failure, but as an infrequent starting and motor cutting starterwhile the rated current is from 0.1A to 63A, it can protect circuitry.

(4)    3VU13 circuit breakers are suitable for any climate and they are designed based on a good operating environment of an enclosed room(e.g. without dust and corrosive gas). If  they are installed in a dusty and wet room, they should be hermetically sealed.
