Basic information about SACE PR121/P E3H32 circuit breaker

Since the search results do not directly mention the detailed special information of the combination of "SACE PR121/P E3H32 circuit breaker", it can be obtained from the general information about SACE PR121/P and the Emax series circuit breakers (E3 is a type in the Emax series ) to make inferences based on relevant information.

(1) SACE PR121/P part

Protection functions and parameter settings

Overload long delay setting (L): I1 = 0.4-1.0¡ÑIn, step size is 0.01¡ÑIn; t1 = 3-144s, step size is 3s (when 3¡ÑI1).

Selective short-circuit short-time delay setting (S) (can be turned off): I2 = 0.6 - 10¡ÑIn, step size is 0.1¡ÑIn; t2 = 0.05 - 0.8s, step size is 0.01s (I2t = k, t = k optional).

Instantaneous short circuit setting (I) (can be turned off): I3 = 1.5-15¡ÑIn, step size is 0.1¡ÑIn.

Ground fault setting (G) (can be shut off): I4 = 0.2-1.0¡ÑIn, step size is 0.02¡ÑIn; t4 = 0.1-1.0s, step size is 0.05s (I2t = k, t = k optional) .

Directional protection setting (D) (can be turned off): I7 = 0.6 - 10¡ÑIn, step size is 0.1¡ÑInt7 = 0.2-0.8s, step size is 0.01s.

Residual current protection (Rc) (can be turned off): Id = 3-5-7-10-20-30A; td = 0.06-0.1-0.2-0.3-0.4-0.5-0.8s.

Over-temperature protection (OT): alarm at 70¢XC, instantaneous tripping at 85¢XC.

Application scope: Can be set to OFF or 50%, 100% or 200% of the phase current, applied to E1, E2, E3, E4/f, E6/f, as well as E4 and E6 with external neutral line protection, etc. .

Structure and performance

Safety guarantee methods: such as swinging out the cabinet door when closed, external protection level up to IP54, various safety locks and double insulation to ensure safety.

Advantages of pole structure design: The innovative pole structure design not only ensures complete insulation between phase lines and between phase lines and neutral lines, but also allows you to check the status of the arc extinguishing chamber and main contacts.

Electrical performance: It may inherit some electrical performance advantages of the Emax series, such as meeting the relevant specifications of the Emax series in terms of rated current, breaking capacity, etc. However, due to the lack of exact information, more precise data cannot be given.
