Page 17: Installation
Installation Precautions WARNING: To prevent electrical shock and damage to equipment, disconnect and isolate power source upstream of the MCCB before installing or servicing the MCCB including its connected accessories. Notice: To ensure correct performance, and integrity of equipment, the installation instructions and recommendations provided herein shall be respected. -
Page 18: Clearances
Installation Clearances WARNING: Exposed conductors including terminals at attached busbars must be insulated to avoid possible short-circuit or earth faults due any foreign matter coming into contact with the conductors. Phase to Phase and Earth Interruption of large currents during fault or normal switching operation produces ionised gases and arcing materials which expelled from the vents at the top of the MCCB. - Page 19 Installation Insulating Distance When earth metal is installed within proximity of the breakers, the correct insulating distance must be maintained, (refer to Minimum Clearance). This distance is necessary to allow the exhausted arc gases to disperse. This could include the mounting plate or side panel within a switchboard. Minimum Clearance Below illustrates the minimum clearance that must be maintained.

Page 20: Internal Accessory Mounting Locations
Installation Internal Accessory Mounting Locations P160, P250 and P400/630 frame sizes have different internal mounting locations for auxiliary contacts, alarm contacts, shunts and, UVTs. Left-side and right-side mounting locations are independent and accept unique combinations. For example, shunts and UVTs may only be mounted on the right side, whereas auxiliary and alarm contacts may be mounted on either left or right side. -

Page 25: Protection Settings
Protection Settings Trip Curve The TemBreak PRO P_TM thermal magnetic trip unit protects against overcurrent and short circuit faults for many types of electrical distribution systems. The P_TM OCR has protective characteristics according to the requirements of the standard AS/NZS IEC 60947-2. The P_TM OCR consists of a standard 2 dial type (blue coloured dials) which features thermal adjustment and magnetic adjustment. -
Page 26: Thermal Protection
Protection Settings Thermal protection The thermal protection is designed to protect against current overloads or surges in power distribution or motor control applications. Thermal protection is an inverse-time protection, labeled as I TM – Adjusting I (Current) The thermal protection trip range is: 0.63 – 1.0 x I according to standard AS / NZS / IEC 60947-2. -

Page 31: Neutral Protection
Protection Settings Neutral Protection Neutral protection is available with 4P P_TM MCCBs as standard. It is particularly useful when the cross-section of the neutral conductor is reduced in relation to the phase conductors. When enabled via the provided selector switch, neutral protection provides both thermal and magnetic protection of the Neutral pole, which follows the parameters I and I as adjusted for the main phases. -
