3.6 Maximum install inclined Angle 5° , it should be installed at the place has no obvious impact and weather-influence.
3.7 Main circuit installation type: III, Auxiliary circuit and control circuit installation type: 11
3.8 External magnetic field of Installation location should not exceed than 5 times of earth magnetic field.
3.9 Installation electromagnetic environment: B type

Note:
1. Only 4P B type and C type products has 240, 250, 248 and 340, 350, 318, 348 accessory code.
2. Only RDM1L-400 and 800 frame size 4P B type and C type product have 260, 270, 268 and 360, 370, 368 accessory code.

3.2 Classification
3.2.1 Pole: 2P, 3P and 4P(2P product only has RDM1L-125L/2300, RDM1 L-125M/2300,RDMl L-250M/2300,RDM1 -250M/2300)
3.2.2 Connection type: front board connection, back board connection and insert type.
3.2.3 Application: power-distribution type and motor-protection type
3.2.4 Residual current release type: electromagnetic type, intantanous type.
3.2.5 Residual current breaking time: delay type and Non-delay type
3.2.6 Rated limited short-circuit breaking capacity: L-standard type, M-Medium type, H-high type
3.2.7 Operational type: Handle-directed operation, Motor operation(P), rotation-handle operation (Z, for cabinet)

Main technical parameter

4.1 Ui=690V, Uimp=8kV, the main technical parameter see Table3.

4.2 Circuit breaker residual current action protection time see Table4

4.3 Overload release consists of the thermal long-delay release which has inverse-time characteristic and instantanous action release, the action feature see Table5

4.4 Accessory device technical parameter
4.4.1 Auxiliary contact and alarm contact rated value, see Table 6

4.4.2 Control circuit release and motor rated control power voltage (Us) and rated operational voltage (Ue) See Table7.

4.4.2.1 Shunt release external voltage is between rated control power voltage 70%~110%, it can tripping the release reliably.
4.4.2.2 When power supply voltage decrease to 70% to 35% under-voltage rated operating voltage, under-voltage release can breaking the line. When the power supply voltage is higher than 85% of under-voltage release rated operating voltage, the under-voltage release will that circuit breaker close. Warning: Under-voltage release must be charged at first, then circuit breaker closed. If not, the circuit breaker would be damaged.
4.4.2.3 Motor operation mechanism ensure that it can make the circuit breaker closed when the power voltage is between 85% -110%, under rated frequency.
4.4.3 Leakage alarming module (RDM1 L-125L, 250L do not have it.) Specification: P5-P6 port for input power-source AC50/60Hz, 230Vor 400V. P1 -P2, P3-P4 port for capacity is AC230V 5A, see Fig1

Note:
1. Mode II can meet special site requirements, users adopt this function after the consideration.
2. Circuit breaker with leakage alarming module, when the leakage alarming is happening, the leakage protection module would function after resetting the reset button of Module II.Fig1.

5.1 Appearance and Installation dimension see Fig2, Fig3 and Fig8.
