The Siemens 7KM2200-2EA40-1JB1 is the flagship direct-measurement energy meter in the SENTRON PAC2200 family. It combines three premium features in one device: 65 A direct connection (no external CTs), MID certification for legal billing, and PTB-A50.7 (CLP) compliant certified load profile memory for tamper-proof energy data recording. Modbus TCP over Ethernet provides integration into energy management and SCADA systems.

CLP: Certified Load Profile for Statutory Compliance

The CLP (Certified Load Profile) designation is the key differentiator from the 2EA40-1JA1 (MID without CLP). The load profile memory records consumption data at configurable intervals with cryptographic integrity protection that satisfies German PTB-A50.7 calibration regulations. This makes the 1JB1 suitable for the most stringent billing applications — where not just the total energy reading but the entire consumption profile must be legally defensible, such as in regulatory energy audits, performance contracts, and sub-billing disputes.

65 A Direct + CLP: The Unique Combination

This is the only PAC2200 variant that pairs 65 A direct measurement with certified load profile memory. The 2EA00-1JB1 offers CLP but uses 5 A indirect input requiring external CTs. The 2EA40-1JB1 eliminates those CTs for circuits up to 65 A while retaining full CLP certification — a unique combination in the SENTRON portfolio for applications like e-mobility charging infrastructure billing and tenant sub-metering where both direct connection and statutory compliance are required.
