The N-pole of four-poles breaker is sited at the right side of the product has four types:
Type A: Without current trip-lease on N pole which making all the time, not closing and opening with the other
three poles.
Type B: Without current trip-release on N pole which closing and opening with the other poles.
Type C: With current trip-release which closing and opening with the other three poles.
Type D: With current trip-release which making all the time not closing and opening with the other three poles.
The thermodynamic release of a circuit breaker provides the feature of inverse time-delay, while the
magnetic release is the instantaneous operation.

Application and Description
TOS1L series earth leakage circuit breaker are one of the new type earth leakage breakers which
have been developed by the company using international advanced design and manufacturing
technology. Suitable for a line of AC50/60Hz, rated voltage up to 400V, rated current 16A to 630A.
and is acted as infrequent changeover of circuit or infrequent starting of motor. The breaker has
overload, short-circuit and under-voltage protective function, which can protect the circuit and the
power equipment against damage, meanwhile, it can provide protection to these fire dangers that
caused by these long-time existed grounding fault that can not be detected by the over-current
protection.
This breaker can be installed vertically(upright) or horizontally(transverse).
Wiring of the breaker can not be in adverse direction, that means power supply line must be con-
nected to terminal 1,3 and 5,and the load line connected to terminal 2,4 and 6.
The rated residual operating current I n and the maximum breaking time can be adjusted on site
according to practical condition.
The leakage protection module still can work normally when the phase voltage reduce to 50V.It has
the same overall size with the TOS1 series breakers, which make the installation more exchangeable.
The breakers are suitable for isolation, its symbol are:
The breakers comply with the demands of the following standards:
IEC60947-1 and GB/T 14048.1 General
IEC60947-2 and GB 14048.2 Low voltage breakers
IEC60947-4 and GB 14048.4 Contactors and motor starters

1. The limiting breaking and arc-over distance includes horizontal and vertical installation.
2. If the three-pole breaker of this series is connected with three phase load, the load can not have neutral
line, otherwise the breaker will have fault action.
3. If the three-pole breaker of this series is connected with single phase load, the phase line will be connected
to the left pole, and the neutral line is connected to the right pole, the middle pole is blanket
The thermal release of the breaker has again-time-limit property; the electromagnetic release is inst.

Application
TOS8 series moulded case circuit breaker is suitable for industrial or commercial power and lighting
with AC50/60Hz, rated working voltage up to AC600V/DC250V, rated current up to 630A. It’s a kind of
economical breaker with the characters of stable and reliable function, beautiful appearance, small
size and long life. It can be used for conversion of line and infrequent starting motor. It can also be
attached to install the accessories which have protection function for avoiding loss-voltage,
undervoltage. The product can install connection line with front board and back board, it also can
equip hand-operating apparatus or motor-operating apparatus to control in a remote distance.

Application
TOS10 Series Moulded Case Circuit Breaker is available in two frame sizes from 25 to 800 amps,
loadline series of moulded case circuit breakers provide overload and short-circuit protection for the
full range of transformer sizes encountered in normal service. The overload and instantaneous trip-
ping elements, adjustable over all wide band, make these MCCBs ideal for many distribution application.
