Safety and protection requirements
For safety and protection reasons, the MCB must meet the stipulated minimum requirements
of the specifications of ABB MV Drives. It is the system integrator's responsibility to ensure
that the minimum requirements are met. The minimum requirements for the MCB are stated
in this note and in the respective MCB specifications, which are available for each medium
voltage drive from ABB.
The safety requirements for the drive are based on the following standards:
- "ISO 13849-1 Safety of machinery - Safety-related parts of control systems - Part 1: General
principles for design, section 6.2.6 Category 3" [20]
- "IEC 60204-1 Safety of machinery - Electrical equipment of machines - Part 1: General
2.8.2
Minimum requirements for MCB and MCB control
- The MCB open and / or trip command has to be wired directly from the drive to the MCB.
• It is not permitted to wire the trip command through any PLC or DCS system if it is not
certified to meet SIL three-level requirements and to fulfill the timing requirements
outlined below.
• Opening of the MCB by the drive must be possible at any time. It is not permitted to
interrupt the open and / or trip command, eg, by a local-remote switch in the MCB.
- When the MCB is in service position, the drive must have exclusive control of closing the
MCB. Local closing of the MCB is not permitted.
- The maximum opening time of the MCB must never exceed the product- or project-specific
maximum time defined in the MCB specifications.
Typical maximum values for the drive are defined as follows:
•
Maximum protection trip time
: 120ms
The maximum protection trip time is the maximum allowed breaking time (open and
arcing) of the breaking device after the open command has been initiated to prevent
further damage to the drive, such as diode failures.
•
Maximum safety trip time
: 250 ms
The maximum safety trip time is the maximum allowed time to ensure safe
disconnection of the main power supply to prevent any hazard to personnel.
