Circuit-breakers E1.2-E2.2-E4.2-E6.2

3 - Environmental conditions

Installation environment

Install the circuit-breaker in a dry environment, without dust or corrosive acids, and so that it is not subject

to shock or vibration.

If this is not possible, mount the circuit-breaker in a compartment protecting it adequately.

For the dimensions to be considered for installation, see the chapter "3 - Installation" on page 166 where

the references for following information can be found:

• minimum installation volumes of the circuit-breakers and derived versions in a cell

• overall dimensions of the circuit-breakers and the fixed parts

• drilling of mounting holes

• drilling of the cell door

Temperatures of the

installation environment

The mechanical and electrical characteristics are guaranteed between -25 ° C and +70 ° C, -13 °F e +158 °F.

Particular weather conditions

The circuit breaker is designed to operate in particularly difficult industrial environments.

It was tested according to:

• IEC 60068-2-1: endurance at low temperatures

• IEC 60068-2-2: hot dry climate

• IEC 60068-2-30: hot humid climate

• IEC 60068-2-52 severity 2: saline mist atmosphere

• IEC 60947 (pollution level ≤ 3)

• IEC60721-3-6 class 6C3

• IEC60721-3-3 class 3C2

NOTE:

the circuit-breaker is suitable for installation in environments with saline concentrations

no higher than 10 mg/m3.

Dusty environments

It is recommended to install the circuit breaker in suitably ventilated switchgear where penetration by

dust is minimized.

In case of dusty environments (dust> 1 mg/m3) second level maintenance procedures must be followed.

Vibration

The circuit-breaker is insensitive to mechanical or electromagnetic vibrations that meet the following

standards:

• IEC 60068-2-6

a) From 1 to 13 Hz with movement equal to 1 mm - 0.04 in b) From 13 to 100 Hz with

constant acceleration equal to 0.7 g - 0.025 lbs

• Shipping Registers' specifications: RINA, BV, GL, ABS, LRs, DNV
